I would like to know if the following setup is combatible :
i5-750
gigabyte ga-p55-usb3
KHX1333C7D3K2/4GX Intel X.M.P, DDR3-1333, unbuffered DIMM. 4GB 7-7-7-20 1.65V
I am asking because most rams on the market are CL9 and 1.5v. Do i have to do anything in the bios or it will detect them automatically?
Also if i want to overclock the CPU am i limited by the 1.65v on the ram? I mean does ram voltage has to do anything with CPU overclock?
-
Hi and welcome to the Gigabyte Forum.
Firstly have you checked to see if the modules appear on the QVL for this board or the board is on the QVL of the memory manufacturer?
If they are there should be no problem running htem. They have an XMP attached so normally it is just a case of going into the BIOS and setting them to use the XMP setting.
You can go over the 1.65V setting if necessary but you would have to ber careful and keep the QPI/Vtt within 0.5V of the memory setting.
-
Thanks for the quick reply, yes i checked the compatible modules and this kit isnt in it. i don't worry about that simply because there are so many ram kits and it is normal some not to be listed. I saw an OCZ with the same voltage and timings (7-7-7-20 @ 1.65v) in that list so i should be all set.
So i am guessing i just install the ram and enable the XMP on the bios and it should recognize the kit. Otherwise i set the timings and voltage manually?
I haven't got the board yet i just ordered it.
-
Yes that's pretty much it. If the memory isn't on Gigabyte's list I wouldn't worry unduly but I would check the memory manufacturer's site for their QVL of motherboards/memory. I take it you already have the modules?
-
Yes and waiting for the other parts to come. I will check the site, i shouldnt worry too much if the board isnt listed right? Kingston are very popular rams they shouldnt be an issue.
-
If you already have them then we are stuck with them I guess and will have to do our best to make them work. ;)
-
Just set the BIOS to spec and you should be fine unless there is some major compatibility issue.
1.65V memory is the norm for these boards, 1.5v memory is just non=performance DDR3l, it's not anything you have to use at all.
Set 1.66V ram voltage in the BIOS, adjust your memory multi and timings, and then you will need to tinker with QPI/Vtt until you find the sweet spot for your CPU (Maybe 1.15-1.3)

You mean dont use the XMP profile to detect em automatically? I know we are talking without an example cause i havent got the mobo yet but i like to plan ahead ::)
-
Lsdmeasap doesn't have a lot of faith in XMP settings so he always likes to use his own. That's fine but if they work why not use them is my reasoning. Besides he can make anything work ;)
-
Oh i see, ok thanks guys i will report once i assemble it.
-
Just got the motherboard in my hands but i am at work currently and will test the Rams later. What i wanted to ask is about the Turbo USB3 function in the BIOS. I am reading through the manual and i am a bit confused. Should i disable that function in order for the PCI Express to run at x16?
It says (if i am getting this right) that when enabled the PCI express runs at x8. Is that true? The setup i am going to use will be a single VGA card at the PCI 1 slot. Should i leave this option disabled for it to run at x16? With this option disabled and Onboard USB 3.0 Controller -> Enabled i still have usb 3 support and x16 PCI express right?
-
You have understood it properly as the USB3 and the PCIE share bandwidth and by increasing one you will limit the other.

That is my understanding of it , yes.

Ok im back. I got the whole PC assembled it recognized the ram at 1333 7-7-7-20 and 1,65v without XMP on. The question now is : do i enable XMP or not? Does XMP only sets the timings and voltages to the correct ones or it has other feautures too? Basically do i need it or not?
-
The honest answer is that you would not notice the difference in real world usage between 1333 and 1600 speeds. However if you want to get the full specifications of the memory in use then there is no reason why you shouldn't enable the XMP settings to do so. XMP only changes the settings of the memory nothing else.
-
Well there is not an issue to choose between 1333 and 1600 because the memory speed is 1333 already, i havent changed a thing. Enabling XMP will take it up to 1600? i am confused... ???
-
Sorry if didn't make it clear. If your memory is rated at 1333 then that is all you will expect to get out of it but if it was rated at 1600 then by enabling the XMP you would expect to get that speed instead. XMP only sets the speeds/voltage, etc of the memory.
-
Ah, no problem the post is slightly old. i have this RAM : KHX1333C7D3K2/4GX Intel X.M.P, DDR3-1333, unbuffered DIMM. 4GB 7-7-7-20 1.65V
So setting manually or XMP is the same difference as i understand.
-
Yes you would gain nothing at all. Sorry my confusion. :-[
-
Ah don't mention it. Keep up the good work helping people.

So the memory people just created these XMP rams with tightened timings and tweked voltages right? You could easily buy a CL9 1600 ram and tighten the timings at 1333 manually if you know how.
-
Yes and many people do. The only problem is that if you buy the cheaper memory you don't know how it is going to perform when you try and run it at a higher speed. They (the memory manufacturers) just choose the best of the memory chips when they make the faster modules.
-
I am replying here although the memory issue is solved, i hope i don't cause confusion on the forum. I wanted to ask 2 things :
First i want a recommendation for a system monitoring tool (fan speeds,temps,cpu-ram frequencies, voltages etc.)
And second about the installation of the SATA2 drive. I have a single 7200.12 baracuda and i am wondering where to install it on the motherboard.
Should i install it on SATA0-6 which is controlled by the P55 chipset or in one of the 2 GSATA slots controlled by the Gigabyte motherboard?
Thanks again.
-
As for monitoring tools it is more of a personal taste. Everest will give you most of the details that you want but most of us prefer to use tools like CPU-z, GPU-z, coretemp, realtemp, etc everyone has their own favourites.
For the best pperformance try to stick to the southbridge ports (P55) SATA_0-6

Ok thats good because i installed on the P55 sata already. About the monitoring i was thinking CPU-Z, GPU-Z and HWMonitor but will check the others also. How can you keep an eye on the monitor while running games? i have a TFT 19" for Windows but i game on an LCD TV 40" on 1080p. i am guessing you extend the display on the TFT have the system monitors there and watch while playing on the other screen?
Oh by the way i enabled XMP because after i flashed the bios it recognized them as 9-9-9-24 1.5v and with XMP it detected them as it should CL7 and 1.65v so i am sticking with it.
EDIT : To be more clear i am asking if there is a way to realtime monitoring while stressing the PC while gaming.

Agreed! That is the best way to go.

Stress testing with a game isn't necessarilly the best way to stress test your computer. It is also more difficult in as much as most games take over the entire desktop and so you won't be able to see the applications even if they are still running in the background. Try using Prime95 and SuperPi and for the graphics try Furmark or Vantage. There are many stress test programs available that you can run in conjunction with your reporting software.
-
Whats up Mantis? I used Prime95 yesterday to see where we at. Ok so it passed all the tests for about an hour so i think i am ok. After seeing that i decided to experiment a bit. I opened CPU-Z to see the turbo mode real time and how it works because i am not planning to OC yet. So when the 4 cores were stressed the multiplier was 133x20 = 2,66 the default speed. turning the 4th core worker off i got 133x21 and when the 3th and 2th core were turned off i got 133x24 = 3,2. So that is my overclock when an app utilizes 1 or 2 cores. I can live with that. I wanted to ask for an advise about the BIOS settings. i dont really get the AUTO option on the cpu tab, should i just enable those options (turbo mode,c1e. etc.? Or should i just load optimized defaults on the bios and just set the XMP ram and i am set? I am asking because many forums and videos go the CPU tab and change the settings from AUTO to ENABLE. Thanks.
EDIT : I forgot to mention that when i updated the BIOS to F8 version it changed the Cpu Clock Drive and PCI Express Clock Drive to 700mv. Do i leave it that way?
-
Yo Dude! Sounds good to me. The settings can be left on auto if everything is working ok. Depending on your memory if it has an XMP setting and it works fine just use it. If not you will have to get your hands dirty and set things manually. Just try riunning the system as you would normally use it and if there are no problems then fine.

You have anything to add about the Cpu Clock Drive and PCI Express Clock Drive? After the F8 update it turned them to 700mv each. i clearly remember that they were 800/900. Did this mean that the bios update returned to the fail safe settings? anyway i will try loading the optimal settings and see if it restores them.
-
Unless you loaded Optimised BIOS Default settings after the update it willl just revert to Fail-safe BIOS Default settings. I am not sure of the exact settings in there but I expect that is what the difference is.

There you have it, i didnt load optimised after the F8 update. I will check first thing when i go home. Thank you so much for your overall help Mantis.

You are very welcome and hopefully that will be an end to your problems but if not just post back again. ;)

Hello Mantis,
Checking back after a while i wanted to say that everything is running very smooth and i decided to change that ;D
Quick question :
I got this i5 750 running on default values for a month now and i think it is time to OC it a bit.I decided to bump the BCLK to 150 because i dont want to mess with voltage control. That will give me an OC to 3.2 -> 3.6 with Turbo. The question is about the RAM.
I have a 2x2GB Kingston XMP 7-7-7-20 1333 @ 1.65v. Now i have XMP enabled and it has detected those values automatically.
If i bump the BCLK to 150 what steps must i do in order to configure the RAM? I assume i can't just leave it to XMP as it is.
-
You can just put in all the settings that you've just given me manually. You might find that it will work anyway but it is no biggy just to change them. The only thing you probably will find is that by adjusting one setting it will mean that you have to start making other alterations too to make it work and keep it stable including upping the voltages. This in turn means more heat to get rid of.

Theoritically speaking a change in the base clock from 133 to 150 doesnt require any voltage tweaking (i read that at Tom's). The question is about the RAM, if i do that i am afraid i have to set the timings,mhz and voltages manually.
