OC Q6600

JoeDredd · 16 Mar 2008 at 12:44

I know there is many threads about tis CPU, but I just need a quick answer to my problem

When I attempt to OC to 3.4 (8x 425), core 3 fails after about 5- 10mins of stress testing with P95 and small ffts, do I need to increase CPU volts? or I have reached the safe max clock of this CPU :confused:

Spec is as per sig, idle temps around 45, load temps (small ffts) with P95 around 70.

Thanks for looking and hoping for some more sound advice

Well 70 at load is the limit I would say mate. you can increas the volts but the temps will go up a little.

Other option is to Lap the CPU or just go back to 3.3Ghz

For me thou those Temps are quite high

Thanks Jamie I think you could be right and I have reached my limits

I may lap sometime in the future but for now I will enjoy

You think those temps are high, I was getting the same temps with an AC7Pro at stock, so I am well pleased now with OCing

yer mate enjoy your overclock ! for the mider of lapping to save a few degrees it probably not worth it, as for me I have took my PC apart that many times it would depress me to do it again!

Aim for water cooling in the future and you can get some nice overclocks and cool temps, and by that time there will no doubt be a 6 core CPU on the market for you to play with.

What do you think is a goood time for the AS5 to settle in? :confused:

it has been 2 days now, if I give it a couple of weeks hopefully temps may drop and I might squeeze a few ghz out of her :cool:

I would either invest in some more case fans or a new case matey. That idle temp seems a bit toasty.

It seems the AS5 is settling as idle temps are 38,37,36,38 so looking better

Some cpu's are just plain hot. Mine idles about that same and I'm on water! Then again this is at 4.1ghz. Its still a hell of a lot hotter than my previous chip.

Have you tried 378x9? This will put less stress on your motherboard but still give you 3.4gjhz.

Thanks for that w3bbo I was thinking of upping the multi to try and get 3.4 so will definetaley give it a go :cool:

UPDATE: Unfortunately no joy down this route, system unstable and BSOD (changing multi & upping volts) so will settle for 3.2 for stability

You might also want to take into consideration what speed your ram is running at. Its always best to overclock one thing at a time then you will know whats causing the pc to BSOD/fail.

w3bbo I have the ram multi set at 2x, and have not touched that whilst trying to increase CPU, when I said multi I meant 8x or 9x as you suggested re bus speed.

Whilst running P95 small fft I get either a failure on core 3 after about 5minutes or when I change multi I get a failure on cores 1 & 3, also load temps increase to 71 ave which is quite a jump from idle temps :eek:

I have increased CPU volts from 1.27 to 1.29 as I dont want to increase volts too much as I know it increases temps !!!

Any ideas or shall I just enjoy my current set up :confused:

Well temps seem to be limiting you as normally I would suggest an increase in vcore as your vcore is very low and to get 3.2 stable with such a low vcore is an achievement in iteslf. Until you either invest in better cooling or maybe consider lapping the cpu then I would stick with what you have.

out of curiosity what should vcore be set at roughly :confused:

my cpu is running 3.1 and idle is 21 and load it's 40.....you need some better colling m8...tuniq tower i would get.

schizo read my sig....already have a TT

.....what is your rig for comparison?

FINAL UPDATE

Right after giving a few tweaks and after 2hr with P95, I have finally settled at 3.4ghz (378x9) @ 1.3v (idle 39,37,38,39 & load 72,69,69,72)

This is as far as I would like to push it as the comp is used nearly 24/7 by myself and family :rolleyes:

All thats left to do is tweak memory multi and I am happy as a pig in #**#

Thanks to w3bbo for his advice and to fellow OCers who have also helped along the way :cool:

Thought the tuniq tower was better than that according to the fan boys here, said it before and i'll say it again, my Zalman wins, ooh, by 5C and my vcore is 1.45v

Thats impressive V3g3tto I did wonder about upping volts to 1.4v and getting 3.6ghz but I am thinking, How long would it last at those volts & temps :confused:

Perhaps if I give the AS5 a few more weeks to settle in at this speed, I may give 3.6 another go and then that will be it

Just a guideline, with your cooler, that chip is safe upto 1.5v for everyday use as long as temps don't get madly high above 70c under stress testing.

1.4v will not even slightly damage the chip, at all, would jsut add a little more heat, so if you want to push it more, you can.

Oh as to the arctic silver, takes about 200-300hrs to fully bed in i believe, though do give it time to cool down and set between heavy sessions, not days on constantly at a time.

ok then I will leave alone for the next week and then try and get 3.6 by upping volts to 1.4v

then I will give 1 more final update if successful !!...feels a bit like a Status Quo tour
