Hi guys,
What bios settings should I change for this memory to work stable?
I followed up some suggestions here and there (icl. OCZ support) according to Prime95 system is not really stable.
bios ver. F12
memory: 7/7/7/20 1.65V
Thanks for any help!

Hi and welcome to the forum.
Firstly I think you need to alter your question in the Poll. Stability is a word not a question and doesn't mean much on it's own. I would advise you to ask the actual question that you want the answer for.
Please list your whole hardware for us to have a better idea of sorting your problem.

Thanks for pointing that out! wasn't sure if I filled out everything correctly........
Anyway, I'm having some stability issues (according to prime95 and the slightly occasional lock-up)
here's my base setup:
GA-P55A-UD3R rev.1
I5-760
OCZ3P1333LV4GK (4GB set)
ASUS EN8400 GS 512MB silent
Corsair VX450W PSU
Don't really want to overclock my setup, just get it stable at full load......

OK. You can edit your original post/poll for up to 4 hours after posting.
Problem wise, are you getting BSODs or just lockups?
Any other issues at all?
How old is the PSU?
What are your temperatures?
Does OCZ warrant the memory to be compatible with your board?
Sorry for all the questions but we need a lot of detail to determine the problem.

Any other issues at all? not really.....
How old is the PSU? brandnew
What are your temperatures? approx. 65 degr.C. at full load
Does OCZ warrant the memory to be compatible with your board? yes, they only suggest upping to 1.65V instead of 1.5V (MB default)
Sorry for all the questions but we need a lot of detail to determine the problem.
hey, I'm the one with the problem right!? thanks for your time!!!
-
Hey, No problem. I do this because I like to help out others who are in a tight spot and need a bit of support. ;)
-
:-* I answered your questions by quoting you......
-
RAM timings are tight try 8-8-8-24 or 9-9-9-24 also try setting command rate to 2 might help.
I think OCZ are just asking too much of their ram sure some will do them timings but other batches might not.
-
Yes you were a bit quick for me and that's saying something ;D
Well if I were to pick something out of all you have given me it would be that the PSU is a little underpowered. Not a lot, but it could just be causing your instability when pushed.
1.65v for your memory shouldn't be a problem in fact even 1.66 at a push. It will show red but is still ok. I would also agree with Peter about OCZ in general.
-
tnx, I'll give the timings a try and report back!
The PSU should be o.k. (or so the salesman told me) since it's not feeding a heavy duty graphics card......but perhaps you're right.....in that case I'll have to return the PSU....
-
PSU is fine.
-
The thing with PSUs is that even if they start off large enough within a matter of twelve months even they have lost a substantial amount of their power output. This is just from degradation of the main capacitors and other components from smoothing out the power supply. So after two years it doesn't stand much chance if it was on the line to start with.Always build in a bit of headroom. I am running a not that much more power hungry setup than you and found that even my new Zalman 750 wasn't enough and had to swap it for a Corsair HX850.
Try the timings and see how you go and if you still have any trouble you know what your next step is.
-
looser timing 8-8-8-24 seems to be stable for now (still testing it with prime95) keep u posted....
If this is the culprit OCZ need to reevaluate their overtight timing suggestions, seem to be quite a lot of people having issues with this brand and their suggested timings.
Point about the PSU taken! tnx

I doubt that was ever the case...not sure what you mean by new Zalman 750? maybe it was faulty?
Other things you can do/test if the timings don't work is disable one or all of these.

Thanks for all your suggestions! test still going strong 8-8-8-24!! ;D normally a fault would have occurred already......

Hi Peter and thanks for the input. No it was definitely the brand new Zalman 750W PSU and there was nothinhg wrong with it I am still using it now in another machine. I think it was all down to the Zalamn having 4 x 12v@18amp lines rather than one and even though the total output was enough each individual line wasn't for booting. It would fall over when trying to boot every time. I bought a Corsair HX 850W and no problem. This isn't the first case by far that I have had (many on this forum)with this exact problem that has been fixed by replacing the PSU.

I water cool anyway so I have these settings disabled anyhow. Thanks for your concern.

That was for the OP.... :P

Oops! My bad, but you quoted me, anyway I will leave the post in case anyone can get an insight from it. Thanks anyway Peter.

That still shouldn’t be a problem I have a 4 x 12v@18amp 650W PSU thats over 3 years old thats powering for about 1 year a i7, 295GTX, 8800GT & six HDD fine. The Zalman might of had too strong protection limits and turned off or the board took to long to power up to send a power good signal and turned off.
All PSU makers have different spec to how long the send a power good signal delay is or when their protection is tripped....but then this was never the case for the OP here.
-
Yes quite possibly you are correct in that assumption. As you say this is nothing to do with the OPs problem so we will leave it there.
-
Sorry guys for not responding earlier......
Tnx for putting me on the right track; I ended up with timing setting 7/7/7/30, VRam 1.64, multipl. 10X
Everything seems stable now at 1333 MHz (memory)
Prime95 gives me the occasional error report but I think that has to do with one of the old PCI cards I use.
Without the PCI cards it's rocksolid esp. with W7 64bit (wow, really quick machine with that op.sys.!!)
All other stability tests report a stable system (with PCI cards inserted)
I'm almost starting to think Prime95 isn't the best testing software for everyone? (but what do I know :-)
Cheers, I'll drink one in your health! ;-)
-
Glad we could help. Try updating the driver for your PCI card and that might make it more stable.
