Im not sure how good these results are but with my Asus P5K Deluxe mobo at the latest bios version i pumping 3.6 ghz out of my Q6600 G0 at 1.4000v. These seem like really good results to me, what do you guys think? Its peaking at 57-58 c with my lapped tuniq tower. Should i go for 3.8?

I personally would stay there, but thats me. Don't forget too much voltage can damage the cpu as well, so heat isn't the only facter in how long the chip will last. Maybe bench at 3.8 or 4.0, just to do it, but I wouldn't run that 24/7.

well i tried 3.8 for the hell of it, im having an odd problem however. 3.8 ghz (423 x 9.0) at 1.4500v nothing crashes or anything but in Prime 95 i get Hardware Failure in the worker threads. Itll just pop up and show hardware failure 1 error and will happen in one thread at a time. My computer dosnt crash or become unstable when this happens.. help anyone. Could it be my FSB NB SB voltage? Ive tried increasing NB and SB to max and it didnt help. However increasing Vcore voltage to 1.4500 prolongs the overclock but still gets the same error.

3.6 is a very good OC , i say dont go higher because your temps may go up and more than 60c which i dont recommend

Run 423x8 and see what happens.

If you know the RAM is rock solid at 846 MHz (which you might also need to test) then it's definately a setting on the motherboard.

Whats ur fsb termination at? pll? also whats your ram operating at...
Ram can sometimes limit an overclock.

fsb termination and pll are at auto or stock, not sure. Should i raise them? Im pretty sure my ram is stable i will check again

It seems the only thing that helps is increasing vcore. The higher it is the longer it takes to get an error.. this seems a bit odd tho. I increased Fsb termination to the next one after standard, same with cpu pll, should i try increasing more? If i cant get it stable at 3.8 with 1.4500 than ill just stay at 3.6, ive got 3.6 at 1.3875v right now .

vCore gets exponential.

I asked for 423x8 stability because it eliminates the CPU from the equation.

see the thing is my ram is corsair ddr2 800 5-5-5-12 stock. Ive had it oced in several machines to 1000 mhz 5-5-5-12. Its at 1006 right now. Ive tested it at stock and its stable. I tried 423 x 8, everything is stable. Anyone know if i should use Asus transaction booster? Some site showed a 1% performance increase.. Should i try to use that or just leave it

Transaction Booster dictates the timings within the Northbridge. When in Auto mine goes to Level 3 at 400 MHz anyways. It works like memory if you have it set too tight the max FSB will not be as high. You can loosen it and get more FSB but it won't always be beneficial from a performance aspect.

If it's 423x8 stable then it needs more vCore, period.

hmm, i had my relax level set to 0 which is the tightest. Maybe if i set it 3 (loosest) i will be able to get 3.8 stable?
Btw: cnumartyr what is ur vcore at, i noticed u have urs at 3.6.

You got it backwards.

Level 3 is tightest, Level 0 is loosest.

@3.6 GHz Memory Transfer Rates (All other things the same):

Level 0: 6875
Level 1: 6985
Level 2: 7068
Level 3: 7185

These are all averages from the two SiSoft Memory Bandwidth results and from my own testing.

Edit: My vCore is at 1.416 at Idle in Windows, 1.400 at load. VID of the chip is 1.2875.

Maybe it's like that on the Deluxe, on mine it's the opposite.


Edit: Back into BIOS.. found what they did.

"Unfortunately, we couldn%u2019t check out Transaction Booster operation with the Boost Level set to 1, because the board wasn%u2019t stable enough in this case."

I have mine on Boost Level 3, which is higher than 0, 1, or 2.

If you Disable it, it will allow you to set a relax level 0, 1, 2, or 3.

I didn't realize there were relax levels, so it was my mistake.
