Post Your Overclock!

[DJG]

I'm definitely impressed with what that lowly 920 can do when coerced! I used to be a dual-Xeon E-ATX board kind of guy, but this thing is more than a match as a desktop workstation at 1/3 the price and 65% power consumption! The cooler gave me a fright it's so tall, the case side cover just about scrapes the top (the MB is vertically mounted).

Here's a graph at the 2-hr mark. It's hot but hopefully not damaging hot ... the CPU hangs around 65-66 and the cores between low-mid 60s and mid-high 70s.

I made some tweaks to my case's air cooling ...

Stock AIR COOLING

This is the Fastest ´´stable`` my system can go, using stock air cooling.

E8500 (3.16ghz) @ 422x9.5=4009ghz - 1.26volts

Satisfied hitting 4ghz. Having tried going higher since the system is on 24/7. Once I get my Q9550 I might crank it up to see how far it can go.

Intel Core 2 Duo E4500 @2.20GHz overclocked to 2.90GHz on stock voltage. Does anyone know what the max safe voltage is for an E4500?

your chip will be good for a 1.5v torture test & 1.4v for 24/7 use

I'm running a Q9550 (2.83ghz) at 3.2ghz on the Intel stock cooler. I changed it from original 333 x 8.5 to 400 x 8. I'm 100% satisfied with my speeds here, and it's 1:1 with my RAM. My temps barely moved from 2.83 to 3.2.

For some days I've spent hours trying to get the max stable OC I can, after downsizing from 12 to 6GB to get more memory speed, since I propbably don't need all that capacity. But I didn't seem to be able to get too much stability and I charted my changes and results to get some clue on which changes were best. I'd go from doing BIOS settings to Windows 7 mem test at the boot menu, and back to the BIOS, making note of settings & results. But the standard Win 7 tests would often crap out.

Long story short, apparently when I removed the three chips spmething was left a bit off. I swapped the ones I had left with the ones I had removed, made sure they were seated right, and suddenly it was hard NOT to get stable repeatable Windows 7 mem test. Wheew!

So now I have a very stable 4020GHz in turbo mode, DDR3-1824 @ 9-9-9-24. It passes the extended mem test, all 2hrs+ of it, during more than half of which it says "I'm 21% done" what's up with that? Maybe they should have a second % indicator for the 21% done time :sarc:. I think it was written by the same programmer who did the progress indicator in the file copy dialog .

The funny thing is my memory WEI is the same as when I had DDR3-1475, 7.9 that is .

....that's a banging OC, DJG


do you have ''HT'' enabled..??

Thanks! Unfortunately, my cooling setup can't handle the temps created by that high a voltage. I need more fans ...

Thanks! And yes indeed! I get 8 virtual CPUs in my core monitor ...

first time i've noticed this thread!

i've got a 3ghz e8400 running smoothly @ 4ghz, by bumping fsb from 333 to 446 and upping vcore to 1.29, all on air cooling, namely a relatively inexpensive arctic cooling freezer pro hsf. mobo is one of the last great abit ip35 pro boards.

it's been running stably for, oh, six months or so, including some pretty intense gaming sessions.

i feel i could go a lot higher with this chip and mobo combo, but 4 gig dual-core action is enough for me at this time; plus, at this speed, chip doesn't get too hot, and fans stay nice and quiet.

right, new Quad installed.....

ive been hammering away at a decent OC now for 8 hrs (the Q9450 is a ''PIG'' to OC on this board)..... this is the max ''stable'' clock i can pull..



finally my P35 chipset is showing its age....lol

now check out the boost in performance, these ''3dmark06'' results are days apart, the only difference is 2 extra cores....




WOW!! ..... what an improvement, have a look at the compared i7 system

That's about a 20% improvement - nice! It does take patience .

Good work mate What settings are you using for 3dmark? ie 1280x1024 etc

 

[skunksmash]

YEP, stock 3dmark settings.....

idle temps are wonderful, load temps are pretty much the same as the E6750, but im still using the AC7 pro.... (the cooler aint doing a bad job.)



gonna try & push up the NB for 3.8ghz

the 2nd core sensor is buggered though, it reads 46c all the time.

gonna try & push up the NB for 3.8ghz

...and then 4.0ghz after that...

As it it is, it pretty much matches my q9550 at 3.8ghz. You gotta be happy with that

the 2nd core sensor is buggered though, it reads 46c all the time.

lol, 3 of my core sensors are buggered now. At first it was just the 4th core, then the 3rd went and then the 1st... they still show movement under load and the tcase sensor is fine, so it's not a huge deal - it's common with this series

oh joy.......


ive had a little play this morning, i have this now stable.....



upped the NB to 1.8v, & added a few volts here & there.... i reckon to get it past this with my P35 board is gonna be a Miracle...

 

[smarteyeball]

oh joy.......

As i said mate, it still shows load temps, so I wouldn't worry about

1.8v??? Is that on air or W/C - seems pretty high :shock:

Different boards I know, but mines at 1.34....
