Hello everyone.
I have a problem here with my overclock, kinda stuck in a dead end
My specs:
Phenom II X4 945 currently @3.45Ghz (FSB 230, Multi x15, Vcore 1.375)
Nvidia GIGABYTE GTX 460 SE (860 core,1900 memory)
Mobo GIGABYTE M57SLI-S4
RAM Samsung 2x2048 Mbytes PC2-6400 (400Mhz) running @3:5 (6-5-5-15-20 2T)

Setup above is sort of a sweet spot for now, tested with Prime95 for 6hrs and still no errors..(I know 12hrs is the thing)
I'm trying to reach stability @3.6Ghz for my CPU, but it seems to be that my RAM is preventing me from doing this. I've tried pretty much everything possible in BIOS, even lowered HT link multi to x1 and RAM freq. to 400 1:1
Prime95 runs for a few minutes and then BSOD comes next..

Is this the limit for my setup I've reached, or maybe it can go further ?
I'd really want to push out to 3.6Ghz for this rig before starting to upgrade haha ^^'

Any advices or solutions would be appreciated ^^

oh duh... DDR2... right.... anyway... i assume you meant 2T not 24 you can bump to 3t you might also try the first number, the CAS at 7

But i might suggest a memtest86 run just to be sure you dont have a chip going wonky on ya.

edit: wait a min.... i just looked back at your original post - you see a difference in the timings you posted and in the timings that are spec'ced? you posted 6-6-6-15 That ram is spec at 6-6-6-18

Any ideas as to which way would be better to loosen up this kind of memory ?
Current default setting is 6-6-6-18-24 1.80V

I've tried to lock the timings at their stock values, tried to keep it on auto and just set the frequency 3x55, 2x66 etc etc
The only thing I haven't really tried is to raise the RAM voltage
Some ppl on the web even say that bumping up the NB voltage can do the trick and keep the system stable without crashing, but I can't seem to find the NB voltage option on this motherboard (it might have none actually)

I was about to upload the CPU-Z shots but imgur and imageshack are going weird on me hah

Its a DDR2 RAM and has the suggested voltage set @1.8V
Samsung PC2-6400 (400Mhz)
Part Number M3 78T5663QZ3-CF7
Serial Number 81966ADA

Update: Bumping up the voltages to 1.9V did not help

I've set the CAS latency as suggested, to 7.0 and ran memtest86 and it passed
And before this I ran memtest with the RAM timings specified by the manufacturer to run @400Mhz and it passed as well.

6-6-6-15 happens when I have the RAM config set to auto
6-6-6-18 is what I set manually (lock it, so to say)
This is my CPU-Z memory tab:

And this is how DRAM tab looks right now:

UPDATE: prime95 still gives BSOD after a few minutes

Able to, I got the RAM voltage from 1.8V to 1.9V earlier and now again with CAS 7.0 and still same BSOD :(

btw do you by any chance know what are these settings for ?

That's your north bridge settings - generally advised to leave alone unless you have aftermarket cooling for your NB - small steps can help in some occasions - honestly, i'm not certain this is one

OC the NB can be tricky. Would not advise unless you have a good guide for your board. Gonna be straight with ya - I'm out of ideas, but gonna try n pass this one to someone that can go a bit further. I'm good - but I'm not a god lol. Though might know a couple people who may qualify....

Well at least I was able to try other settings that I'd not figure out lol Thanks anyways!

Funny thing btw, setting up the FSB from 230 to 234Mhz without modifying anything else is actually keeps up in Blend test on prime95 :D But once it is 240 and above = BSOD
