i think its the Biostar thats making it possible - its a great motherboard.

I've managed to push my 920 to 3.5Ghz 100% stable without having to change anything in the BIOS at all but the FSB. All volts are on auto and I only have the intel stock cooler (albeit I do have some mx2 paste under it). I'm very pleased! The temps are about 31 at idle, i havent measured it at load yet but it must still be quite low because I am on stock volts..

You sure your on stock if its on Auto?

Don't forget the bios will scale voltages with baseclock. Auto settings should be monitored, don't just assume all is well.

Dont know why your messing about with tiny increments and hours with Prime 95.

Just get LinX and run it after an overclock. If your unstable you will know about it within the first 10 minutes.

Most i7s start getting into problems around 3.7 ghz - 4.0ghz with vcore the most likely problem.

When HT is on, LinX only achieves 50% load and does not tax the CPU anywhere near as much as Prime95 on blend of OCCT.

Linx does if you set the number of threads to 8. You need the newer version of it.

Not here it doesnt with HT on, testing all memory in 64 bit mode it achieves 100% load and gets it about 5c hotter than Prime 95.

You must be doing something wrong if your only seeing 50% load. Try this:

Aye that it is, but auto doesn't necessarily mean it's at stock. Check what it is on that hardware monitor thing after it posts.

ahhh crap i forgot to actually check....

Vcore 1.41 :eek:

ouch - i should really do something about that! the temps are still acceptable though

Helios1234 · 13 Feb 2009 at 00:14

Idle may be low due to speedstep, mine idles at mid 30s but loads at 80 degrees during LinX at 3.8ghz.

Thanks for the advice... I've updated and am now getting 100% load.

ok I now have 3.57Ghz stable on 1.328 volts which isnt too bad at all. Whats the max the DRAM voltage should be again?

1.65v

Chandler_90 · 13 Feb 2009 at 07:50

3.4Ghz stable here..

9Hr Prime run, max temps of 71, 69, 67, 68

Chandler_90 · 15 Feb 2009 at 17:56

Short msg as i'm on my ps3 typing this .. motherboard broke on friday b4 i could test out my new gtx295. rma'd with ocuk. expecting replacement on thursday.

thevet · 22 Feb 2009 at 01:57

Here is my bios which i meant to post a while ago...this is 3.8 and its rock solid,very stable

This is pictures from bios 1001
I am currently using bios 1101

i have exactly the same settings in the new bios 1101,i have found with bios 1101 i can lower my cpu voltage a little more than i had in bios 1001 that you see in the pictures.....

my cpu voltage in bios 1001 in the pictures is 1.375v....but in the bios 1101 that im using now i have it set at 1.350v....its a little lower and gives me the same results and is very stable....1.350v i tried in bios 1001 and it failed to boot into windows

This is for the rampage 2 board

anjs · 23 Feb 2009 at 22:26

So here is mine

AI Overclock Tuner - X.M.P
CPU Ratio Setting - 20
BCLK Freq - 200
Dram Freq - 1603
CPU Voltage - 1.375
QPI/Dram Voltage - 1.375
Memory Volatge - 1.64

Hyperthreading - on

Idle - 35
Load - 70

Prime stable for 5 hours

And 3dmark06

Chandler_90 · 25 Feb 2009 at 13:13

Very nice clock there anjs.

Makes me wanna start clocking mine again.. I've got it completely stable at 3.2.. temps never go higher than 60....

Nick1881 · 26 Feb 2009 at 23:40

I bought another 920 CPU off MM to try.

I have it up to 3.8Ghz with HT on same as my last chip but now at 1.30v in windows, rather than 1.39v, although I have spent a lot longer with it and tweaked a lot of other bits too so I'm not sure its the chip. I'm going to try the latest bios then try for 4Ghz with HT on.

GunRunner · 9 Mar 2009 at 20:35

I carried out some experimenting today, and this is what I managed.

I did not expect it be stable using 211x19 giving 4.0ghz. Only time will tell. My signature gives the 3dmark06 for what its worth. The TDP is only 114w as opposed to using the 20 x multi and getting TDP of 130W @ 3.8ghz and 3.9ghz. I could not get 4.0ghz using 200 x 20 that is why I used 211 x 19. Rather strange!

Chandler_90 · 10 Mar 2009 at 08:25

Nice temps!

Mine was hitting 76 at 3.4 on full load.

1.3v is nice too.. looks like u have a good clocker there!

Whats the code of the CPU?

Competitor rules
