You will probably need to raise CPU volts. http://processorfinder.intel.com/List.aspx?ParentRadio=All&ProcFam=0&SearchKey=9550 (http://processorfinder.intel.com/List.aspx?ParentRadio=All&ProcFam=0&SearchKey=9550) click on the apropriate one which matches your sSpec number (should be on side of processor box and on cpu itself) that will tell you what safe volts you can operarte within. You may also have to raise FSB and NB volts.
-
Thanks for the reply. I upped the cpu voltage from 1.25 to 1.28 and tried at 3.00ghz, system would not boot. Not sure where the North bridge timmings are? I would of thought it would be easy to raise the cpu to this. I have noticed that the memory timing changes from 800 to about 840'ish (forgot to write it down). Could this be the problem?

Any one with any info on the memory speed going up
Should it or is there a setting so the fsb goes up on its own without increasing the memory speed.
I'm new to this and thank any one who can help

Hey sorry I haven't been around much personal problems and such like getting in the way!
Are you using the latest BIOS? If not update to latest one, then take things from there.
-
Thank you for the reply. I have the F4 bios which seems to be the most up to date bios.
Regards
Mark

If you leave memory as default and put the FSB at 400. This will make your fsb:ram 1:1. Put the multi at x7. This should give you a speed of 2.8ghz. This is near enough the default speed of the q9550. Becuase of this you should be able to have the voltage pretty low. Once you get it to boot on 2.8ghz, try increasing the Multi (each 1x increase will be 400mhz). Though when you do this you may have to increase voltage. Once you get upto 8.5 multi it will give you a speed of 3.4ghz.
Let me know how you get on, on another note, I'm not sure what that board is like for overclocking quads?
-
Thanks for the reply.
I have tried that and the pc will not boot. I think its the board so I am going to leave it at stock. The pc is quick enough anyway but just wanted to see if I could get a bit more out of the cpu.
Regards
Mark
-
So it wont even boot at stock speed with non-default settings? (fsb 400 multi x7)
-
Hi, I tried it again as settings you said, system will not boot on the following setiings
cpu multiplier = 7
fsb = 400
I think the board is no good for overclocking, worst luck....
Mark
-
Hmm this really is strange. Could possibly be a slightly underpowered psu? Unlikely though. Try just using 1 stick of RAM, unplugging graphics card and using onboard. Compleatly disconnecting all dvd drives and just having your OS HDD plugged in. Then obviously keyboard, mouse + monitor.
If you can get anywhere with that it could possibly be psu problems. If not, put everything back to stock, run memtest + prime95 (on all options).
Other than that i'm pretty suck, anyone else wanna help? :P
-
Sorry for posting in the other forum. Just baffled why I can't get it to work at a bit faster speeds.
I am just going to try and start the pc with nothing but the essentials atached to the motherboard.
Mark
-
I removed all drives, cards etc and fans and got exactly the same results.
8.5 x 343 is the max.
I tried lowering the memory speed and could not get past the 343 fsb.
I think you might be correct with the fsb limit.
Regards
Mark
-
Put everything back to stock, run memtest + prime95 (on all options). If you have (or can borrow) a different PSU try that. Otherwise it is looking that like board hits a FSB wall :(
-
I tried it with another psu. It is a cheap branded 500w but same problem.
I am going away for 10 days but will try the memtest and prime95 test when I get back.
Thank you for your help and will post my results when I get back

Yeah give that a try, other than that i'm pretty stuck on what to suggest O_o

There is a setting in the bios to UNLINK the memory FSB and using a divider ie, 1.1. 2.2 ect use page up page down and you will see the resulting memory speed, don't forget it's twice the memory rating, shows 400 as 800,
try it ;D

Oh yeah I totally forgot about that! *smacks forehead* this could be why hes having problems as its automatically clocking the memory further than it can go. I feel like such a prat :-[
-
Don't matter :-[ we can only try our best to help, :-X
Much easier with the PC in front of you ;)
-
Arghh I'm such a numpty! I didn't read the bit when he said his memory speed was increasing. I'm 99% sure this is why its not overclocking.
uggitt: many apoligies for getting you to do stuff you probably didn't need too! :-\ :-[
-
Thank you for the replies. Just got back off my hols and ready to have another go.
Does anyone know what the setting is to unlink the memory in bios for the board I have. I think I am going blind as I can not see it.
Oggmonster, thank you for all your help and also to Pottypete,
Regards
Mark
-
It should be around where the divider settings are...? Should be something like linked, unlinked and auto
-
With my Gigabyte board you have hit Ctrl & F2 to access MiT advanced settings,
otherwise wot e said ;D
Hope you enjoyed your holidays ;D
-
May also possibly be under something called "system memory multiplier" ?
-
Infact i'm pretty sure thats it, I downloaded the manual for your mobo. Under memory freq it says; ".........automatically adjusted acording to Host CPU Freq (mhz) and memory multiplyer settings"
-
I have tried shanging this setting before. Any ideas which is the correct one i need. It always seems to increase the memory when raising the fsb.?
This is what it says in the bios manual and I am not sure about the (G)MCH freq latch settings
System Memory Multiplier (SPD)
Allows you to set the system memory multiplier. Options are dependent on CPU FSB and the (G)MCH Frequency Latch settings. Auto sets memory multiplier according to memory SPD data. (Default: Auto)
Regards
Mark
-
What are the options there? Anything that says 1:1?
EDIT: try putting CPU host (fsb) at 400 then system memory multi at 2.0b? That should give u a fsb of 400mhz and memory speed of 800mhz which is 1:1 ratio.

I tried the aboveand i do get the 1:1 ratio. But as soon as i increase the fsb, so does the memory speed.
"It should be around where the divider settings are...? Should be something like linked, unlinked and auto" - Cant find antyhing relating to this and i still think this is the problem
Once again, thanks for your help
Mark
-
Thats really weird. If you put the fsb at 400 at mem at 2.0b, that give you a 1:1 ratio yet it still increases the speed? :S If its 1:1 ratio it should remain the same (bear in mind 800mhz ram is actually 400mhz because its double-data-rate)
-
here are the settings in the bios from the manual. Oggmonster or anyone else, any ideas on how to stop the memory frequency from gaining whilst adjusting the cpu host frequency? These are not my settings but may give an idea on how to do this.
Robust Graphics Booster [Auto]
CPU Clock Ratio (Note) [10X]
Fine CPU Clock Ratio (Note) [+0.0]
CPU Frequency 2.66GHz ( 266x10)
******** Clock Chip Control ********
>>>>> Standard Clock Control
CPU Host Clock Control [Disabled]
x CPU Host Frequency (Mhz) 266
PCI Express Frequency (Mhz) [Auto]
>>>>> Advanced Clock Control
******** DRAM Performance Control ********
Performance Enhance [Standard]
(G)MCH Frequency Latch [Auto]
System Memory Multiplier (SPD) [Auto]
Memory Frequency (Mhz) 667 667
DRAM Timing Selectable (SPD) [Auto]
Thanks in advance,
Mark

Does it do the same with all system memory multiplie options? I'm almost out of ideas O_o would be good if anyone from gigabyte could shed some light on this?
-
Hi Mark,
System Memory Multiplier (SPD) [Auto]
set to (spd) looks like the only option,
PCI Express Frequency (Mhz) [Auto]
Set to (Mzh) Just make sure this does not exceed 99Mzh, if you have a PCI express card installed,
It's all trial and error this overclocking malarky, be very careful as you could damage your hardware if your not clued up,
search for overclocking guides for your setup,
(measure twice, and cut once),

I have searched for overclocking my board but no details out there. I think the board is just no good for overclocking. Might get a different board in the near future if I cant solve this. Maybe an Asus as they are renowned for overclocking.

Personally I would stick with gigabyte. Ive overclocked friends PCs with Gigabyte boards with no problems. Like you said maybe its just that board in particular. If its making the memory faster maybe it would be worth trying faster memorys so it's able to cope?
I'm sorry we couldn't get this sorted for you :( Would be good if someone from Gigabyte could let us know the situation with that board :)
-
I have sent a message to gigabyte via their website about trying to stop the memory going up while increasing the fsb.
Hopefully they will come back
Thanks for your help and if I get it sorted I will let you know

Here is the reply from Gigabyte technical help, do you think it could be this?
Answer : Hi,
It is because of the EIST/C1E function, the system will automatically down the CPU frequency/voltage when system is at idle or no loading. Please try to disable both option and check again.
Question : Hi, thank you for the reply.
Can you tell me the setting in the bios so I can increase the fsb with out increasing the memory speed. I have tried setting the System Memory Multiplier to 2.0b to try to get a 1:1 ratio but as soon as I increase the CPU Host Frequency (Mhz) the Memory Frequency (Mhz) increases. This is what I am trying to stop, to keep the memory Frequency (Mhz) at 800.
Best regards
Mark
-
Would be worth a try I guess and also disable speedstep. These are all power saving options which you can enable if you wish when stable overclock is achieved. If it doesn't work point the technical team at this thread :)
-
You don't ever want energy saving on as it causes stability issues and can cause damage to your CPU/Board when overclocking.
~Bex
-
All these settings are disabled.
So no joy there. I have contacted gigabyte and sent them the link, so heres hoping
Thanks again for your help on this
Mark

Bah how annoying! Let us know what they say. Just another thought...Did the board come with any clocking software whereby you can overclock in windows? I generally don't touch overclocking software..but maybe an option/worth a bash?
-
Here is the reply from Gigabyte. Seems to be the motherboard due to the P41 chipset. They have the same problem, I think another board may be needed if I want to o/c
Gigabyte Reply:
Hi,
According to related department, that P41/G41 chipset cannot do too much over clocking for CPU Host frequency.
We have tested other G41 chipset motherboards, they all fall on the same 340 FSB limit.
Maybe you can verify this issue with other brand motherboard with G41 chipset as well.
Here is our system configuration:
Motherboard: EP41-UD3L rev 1.0
Bios version: F5C
CPU: Intel Q9550
Memory: Crucial Ballistix DDR2 800 FSB 2 GB @dual channel
OS: Window Vista 64 bits.
Test done:
1. Bios setting to 340 FSB (attached BIOS Setting.jpg).
CPU clock ratio --> 8.0
Fine CPU Clock ratio --> +0.5
CPU HOST CLOCK Control --> Enabled
CPU HOST Frequency --> 340
Performance enhance à Standard
System Memory multiplier --> 2.4B
DDR2 Voltage control --> (2.00V) --> Base on your memory spec.
FSB Over voltage control --> (+0.1V)
GCMH Over voltage control --> (+0.1V)
CPU Voltage Control --> 1.25625V
Check system information (attached 340-OC.jpg)
2. Check on other G41 series motherboard like EG41MF-s2H (similar configuration above), same limit to 340 FSB (attached G41-at-340.jpg)
-
Aw thats a shame :( Atleast Gigabyte have cleared it up once and for all. You could sell that board and put the money towards a P45 chipset board perhaps?
-
Is it possible for a dual-core with a 1066 FSB to have a 266 MHz FSB wall? In my case I've tried almost everything to overclock an E6300 pentium processor (2.8 GHz)...
