Yes. I know....look at SVT's now.
Maybe it was a bugged run, but it still won in 7 of the 17 tests...
I was having power issues at first with the FX and dual 7800GTX's before I swapped out the OCZ600w to teh PC P&C 850w. I don't remember when I ran the FX bench if it was before or after the power supply swap.
I have 2 other runs on the FX with both other runs about the same in nature scores. 1 was with the GTX's and 1 was with my 6800GT's highly overclocked..
I'll run a few more tongiht and see if there is any difference...
anyone got a 4400 x2 with a bad second core? btw, reinstall winxp and everything is ok now, sheesh. anyhow the second core on my 4400 x2 is bad :(.
How are you determining this "Second core is bad" there is extensive information about X2 floating around. Basically you WILL find that while you will fail on a particular core during dual prime you can prime all day all night on that ONE core, same OC speed and it won't fail :fact:Quote:

Think about when in the near future you will have an SMP app push both those cores 100% for 8+ hrs, probably not going to be very soon.
Do definately test both cores separately for a long time to make sure though
i did test both cores seperately and at the same time. cpu0 or core 1 can run prime95 for hours. cpu1 or core 2 failed prime95 after the 1st iteration. this is on default speed btw. i'm not bashing amd or anything here, but this dual core seems defective to me.
Ok well that certainly is the first I've have heard of that yet. Sorry to hear that :( This reason is why I ran my X2 (first AMD I've owned since the pre-1ghz days) at default for a couple days of testing to make sure I had nothing defective @ $632 it marks the second most expensive CPU I've ever purchased (I think I paid $700 for a P2-300 way back in the day) I wanted to ensure my chip wasn't defective and if it was there would be no way they could throw the "you overclocked it out of warranty" thing on me.Quote:

Hello companions, I don´t know if to buy a 3800+ x2 with following step:
ADA3800DAA5CD
CCBWE 0525XPMW
1245498G50098
or sandiego 3700+ of the week 0517UPBW . What would do you?
The processor would go exclusively destined to play with one 7800 GTX.
I wait for your answers with attention.
A great greeting to all and thanks for everything.
I seriously doubt there is anyway for them to tell if something has been overclocked or not, if there was a register or something it would immediaetly reset when it was powered off... and i really doubt they are going to put some kind of rom or something in there to hold the frequency the chip was last running at... and otherwise they'd have to take the entire chip apart and examine it to see what happened, which is also extremely unlikely.
what do you plan to do with it? Do you mean play games?Quote:

well i'm the unlucky one. this is the 1st most expensive cpu i've ever purchased and i don't want a defective product. afterall, amd means quality right. i don't care if they check the cpu once i return it back to them. i didn't do anything or inflict any damage to it. it still works, but not stable dual core. i don't want to pay full price for dual core and only get 1 core working.
I agree, I hope you bought the retail version of the chip which is boxed and includes the HSF, that way you can do the RMA online with AMD and get a replacement directly, OEM is not something I'd ever do after reading the pain to get a replacement not to mention only like a 90day warrantyQuote:

Let me tell you it makes a huge difference in XP to me, used to be on startup of XP I'd hear the standard windows theme song then 5-10 seconds my audigy sound music now there is approx 1 sec delay and sometimes one is almost overlapping the other. Everything in XP much snappier and fluid, and I have the gaming CPU I wanted with my XFX 7800 GTX Extreme 500/1400!Quote:

From your sig I am assuming watercooling? hmm maybe some of you with air cooling or water cooling can answer this for me so I can compareQuote:

Specs 246x11 2.7ghz 1.586v X2 4400+
Just want to make sure I don't need to pull the HSF / chip and redo it, in comparison same case and airflow my wife's PC (P4-3.2EE runs 41'C priming) and it's at 1.6v overclocked from 3.2-3.46, using the XP-90C, that same chip with my old thermalright pre-xp-90c did 3.35 stable prime
Does anyone think the XP-90C is better than the XP-120 I've read that the XP-120 was best due to large fan etc and massive amount of fins on it. Is it worth the time to pull HSF off both and try the XP-90C on my X2 to see if I can lower temps?
you must be brave to take the ihs off :). for something this expensive, i'd treat it as a piece of gold :).
Right now with 1.6v and watercooling, dual priming @ 2.82 its running about 48 degrees with IHS on. I'll probably take off the IHS tonight, and will probably be about 39 degrees while stressing.
At idle its about 36 degress...
Damn well I hope someone with good air cooling can confirm today what they are running for temp, because that's quite a bit difference of 10'C but it is watercooling though. I just would rather avoid the hassle of removing the XP-120 and XP-90C if it really is a nominal temp for good air cooling.Quote:

I have the DFI N4 Ultra-D board. I have the big tornado for a cooler. What else could be causing it to time out? Is my 2nd core that bad?
1. Sell your mobo cpu and ram on ebay and buy a Pentium D.Quote:

Two things I HIGHLY doubt Dr. Ruiz would ever say...buy a Pentium D or give us more info so we can help the OC?!Quote:

There's my info. Let me now if you need anything else. I dropped the voltage back down to normal, and went back to 2.5 where it is stable. Prime95 works there.
Any sort of memory divider? I'm not sure your memory can handle 237, tbh.
I wasn't using a divider. Would that affect Prime95 though?Quote:
