I have to agree with Sen, I would also RMA it why lap it an really void the warrenty. Lot of cabbage for a messed IHS
 
I will be staying right where I am at now. It is 100% stable, and I am very happy with it. The heat/IHS issue is gonna keep me form bumping the vcore any more. I am very lucky this chip responded so well to the low well vcore, cause if I had to put 1.4 or higher it would have melted in the socket :)

Nice, are you going to keep the chip or fix the IHS issue? 4.7Ghz would be a nice little goal :).


The way this things is running now, I more then likely will be keeping it. I wish it was cooler, but if it continues to run 24/7 for another week or so, then I may bite the bullet and attempt to fix the IHS. The way I see it, this thing is at least 8c hotter then it should be. If I could knock those 8c off, 4.7 would be easy. Hell It loaded windows at 4.7 on default vcore.

On a side note, those two 120mm fans we added to the side of the case dropped my video card temp by 5c. Amazing! :)
 
BTW, take some pics of your modding! Sen told me it turned out perfect :). Also, if your going to fix it / keep it, I would recommend lapping it (Only if you arn't going to RMA it)
 
I would lap it or rip off the IHS of a good clocking chip before RMAing it. :)

Nice clocks... what are your idle/load temps on stock volts and stock clocks? What are your idle/load and voltage on your main OC? Dunno if it was mentioned...

Currently at 1.325 volts - Idol is 43c, Load from PcMark04 was 63c. Load from dual Prime Instances was 68c!

I don't know what load was at default settings, but Idol was 40c.

Have you made a decision yet? :)

Also, what's stock voltage..

Stock voltage is 1.300

havn't compeltely made up my mind, but if someone made me an offer on it I could not refuse, well you know, everything is for sale for the right price :)

Well put hte 651 on the new water setup. Just getting started with it, but here are a couple screenshots.

275fsb @ 1.375 vcore. Did pcmark with ease.

Minor upgrade. Wanted to be over 4.7ghz so i bumped it to 277 fsb. Left vcore the same at 1.375. You can see the extreme difference at idol in my vcore on this board. CPU-Z read 1.43 at idol!

Actually 4.9 seems to the best i can do with it! Anything over 290 fsb and it wont boot
4.9 was a "hump" for me too...how much Vc are you running for 4.9? Mine absolutely needed 1.55Vc to be stable enough to PCMark04 @ 5GHz. 1.525-1.535Vc it would start and not score. What are your load temps?

Yeah, that idle Vc stinks. I had to wait to redo my vdroop mod to set the Vc any higher because it overvolted so much at idle...would've been 1.60V easy set at 1.55.

yea I didnt even try to set it above 1.475 cause of the droop problem. So I guess that is the reason.
 
Nice results surf. Can you see a big difference now that your on water? I am really considering a water cooling setup but funds are a little tight until i sell one of my cpu's. :) I'm also considering lapping my 661 since it's not selling. :eh?: My IHS isn't that bad but it can only get better after a lap job.

Yea another 200mhz stable at lower temps. Will do up to 4.9 now, but my droop worries me so I dont run it there.
 
just wanted to say, i got 7302 with my 920 at 4.0ghz... why is this chip scoring lower then mine? i am STRONGLY considering picking up a cedar mill in addition to my 920, then selling the 920 if the cedar mill performs better. but if im scoring higher with a crappy video card, and not the best ram in the world? ill keep the DC.
