AMD® Athlon™ II Overclocking Thread

Can you lower the 3.5GHz vCore down any lower than 1.520v? . . . it may be the chip is just thirsty but I'm running a similar config at under 1.400vCore (1.392v) . . .

iTek · 19 Apr 2010 at 19:03

Have not tried, will try immediately, I said if I could get to 3.5Ghz i'd stop but with idle temps at 16 degrees and load round 30 it would be rude not to keep going... wouldn't it?

Update - I have reduced the vCore amd have ammended the screens above, will check to ensure system stability is still present and include screen shots of blend runs when complete.

Here ya go iTek . . . . consider this a weeks worth of testing!

AMD® Athlon™ II X4 620

@ 3.6GHz (13x277) + Tweakage!

CPU/CPU-NB/HT-Link/DDR2

3601/2216/2216/923
3601/2493/2216/923
3601/2493/2493/923
3601/2493/2493/1108

sorry don't follow you... you have set me some homework?

CPU/CPU-NB/HT-Link/DDR2

3601/2493/2493/1108

This one is a certain no no lol.

I'll be doing similar tomorrow. Got a BSOD last night while the rig was running but passed at 6 hour prime blend so i'll drop the multi down to 10x maybe lower and run it at the 261 fsb it failed and last night and leave prime running while I sleep due to being on nights

iTek · 21 Apr 2010 at 20:24

Got some new memory arriving tomorrow, hopefully I will be able to get it running with a faster memory divider, if not I just spent some money for nothing...

Frozennova · 22 Apr 2010 at 06:50

Good luck mate, i'm both memory and mobo limited, won't post above 271 and prime fails straight off if memory is anything above current settings.

Was rather annoying as I could have had 1600mhz patriot sector 5 for another fiverif I wanted for it to come off pre-order.

So much for gigabyte boards not having an fsb hole below 300.

iTek · 24 Apr 2010 at 12:20

Ok, so memory came and managed to use a better memory divider.

Here is the latest.

iTek · 27 Apr 2010 at 11:51

Update - Manage to pick up another Athlon X4 620 - this time it was one with the L3 cache, just thought i'd share some initial screens.

What do you think - obviously running quicker then my present 620 with less volts and the L3 enabled.

Trunks9486 · 27 Apr 2010 at 20:02

Nice! You effectively got a Phenom II over there. Congrats

Now try to push it higher!

iTek · 27 Apr 2010 at 20:48

Indeed - allthough I wont be able to go much higher, simply down to limitations, locked multiplier been one bottleneck and DDR2 possibly the other and 900mhz overclock is not bad anyway

Big.Wayne · 27 Apr 2010 at 21:16

Hey iTek,

nice to see the progress you been making!

However . . . now you unlocked your latest chip to a Deneb you no longer meet the criteria for submissions to this thread

Sargas
Regor
Rana
Propus

Please post your results in the AMD® Phenom™ II Overclocking Thread . . . . (Welcome Post here) . . . keep up the good work! :cool:

iTek · 27 Apr 2010 at 21:41

Ok.

Although I'm pretty sure its an athlon propus with locked multiplier of 13.

Big.Wayne · 27 Apr 2010 at 21:55

Hey iTek . . . Propus has no L3 cache, only Deneb has that, it's different silicon and not really comparable with Propus in the strictest sense . . . it's all good though, looks like a great chip, now you just need to work out a way to achieve 308MHz HT ref. Clock and get a sniff of 4GHz!

Frozennova · 27 Apr 2010 at 22:50

I know its not strictly meant be posted here but can you wprime and fritz comparisons between the chip with L3 unlocked and locked to see the difference it makes

iTek · 28 Apr 2010 at 07:39

Big.Wayne - 308Mhz HT no problem NOT lol. Having said that, this board does support DDR1200 but i'd after change the memory divider again with this memory or buy some PC-10000 :-)

, do you know what the max voltage is for these chips?

Frozennova - i'll do some and mail you them if you want, i'll be concentrating on the MAX overclock before disabling the L3 and running those comparisons so just bare with me please.

Frozennova · 28 Apr 2010 at 15:07

Yea theres no hurries mate, it may give me a choice to justify upgrading to Phenom II for a chance unlock.

Don't suppose you run folding@home do you?

1.55v is considered safe but 1.5v is max for 24/7

iTek · 28 Apr 2010 at 16:43

I don't run folding... what is it mate?

Frozennova · 28 Apr 2010 at 19:10

Its a distributed computing project. A client runs on your system in the background as a low priority process run scientific simulations for Stanford university. Your system is assigned a Workunit which it then crunches unnoticed in the background. Each workunit is work a set amount of points dependant on the speed your system crunches compared to the benchmark system (i5 750 IIRC)

You have the option of running multiple uniproccessor clients or one SMP ( multi core) client. SMP units have tighter deadlines but have greater rewards.

I've enjoyed reading this thread. Has anyone had a go with an Athlon II and an 890 based board? Many of the 890GX boards I've read reviews on (ASUS, ASROCK, Gigabyte) have exceeded 300Mhz on the bus speed with Phenom II CPUs, so it would be interesting to see whether the same can be done with the Athlon IIs and if 4Ghz is attainable!
