if i were to buy a random new CPU ...X2 3800 or opteron 165? these X2 results are nice (but so are the opteron ones :rolleyes: )

this somewhat seems like what i encountered with the ultra-d. Once I tweaked the mem timings, I had no problem with 3.0ghz. However, before I tweaked the memory, I was hitting a wall at 2.95 and no matter what volts I used I couldn't hit 3.0ghz.Quote:

I like this CPU I would be interested in one of yours for myself.
rockin'...just the data i needed to know.
bjonz, let me know by PM what you want to do.
dave
my memory controller rox with my new AD0
my ballistix passed 4h47mins of memtest @ DDR600 2.6v :eek:
the only thing bad...it's not windows memtest stable :(
any suggestions to get my memory stable ? already tried 2.7v and 1.47v cpu (instead of 1.45v)
Raise MAL/RP and/or adjust drive stengths.
Well I just started playing with my new ldbhe 0601 xpmw and it is not the greatest so far. Prime failed after about 20 minutes at 2600 at 1.32. I bumped vcore to 1.36 and prime passed 45 minutes until I stopped it. Now priming at 2650 1.39v. Will report in a few.
it should be a nice clocker on phase
I just got today a LDBHE 0606EPMW I bought here in Portugal. I hope I can reach 3ghz with my TT.
I can't test right now cause I also sold my graphic card... I hope I can get a 7900GT tomorrow to replace my old.
I will keep you informed
Ok, so Last night I did some testing on the LDBHE 0601 XPMW that I received and it took 1 voltage bump to be stable at 2600. Then 1.39 for 2650, and 1.44 for 2700. When I would try 2750 or 2800 with up to 1.5v ( the most I tried) either one core or the other would fail randomly..probably due to heat load showing above 42c on my ultra d. this chip was a "T" chip and would probably be suited to higher end water cooling or phase. Now I have to decide whether to ebay her, or find someone with phase that wants a good cold chip.
Now on to today's adventures....
I just unpacked my new LDBHE 0601 TPMW which is a "N" chip. I started with a quick 20 minute prime at stock at 2600, and all was good.
Then I did 10 minutes at 2700 at stock (1.32v) and impatiently stopped it to try more.
Now as I type this I am 1.32v @ 2800 dual prime!!! This baby is a keeper fo sho!
I'm about to have to go back to work for 2 hours, and I'll leave it running at this and report back in a few.

i have the same chip as fullup3 also with a "N"
but i cant figure out the temps on my Expert yet:D
Looks like the 3800's we've got right now are all "T" chips. I wonder if that actually makes a huge difference.
Someday, it sure would be interesting to test 100 chips or so, so that we could do a statistical analysis to see if stepping really matters, T/N, and if burning in actually helps.

it sure made a difference in the ones I just got.
the "T" wanted alot of volts to scale, and this "N" is testing dual prime right now at 1.45v 2950mhz.
same...2950mhz 1.45v
No comment.
Don't get me wrong, I don't doubt what people are seeing. My point was that it would be very interesting to have *many* chips all benched by the same person, on the same equipment, under the same conditions.
So, all I meant was that it would be very interesting to be able to remove all those variables, so that we could get actual "scientific" data to prove (or disprove) our "anecdotal" findings.
I agree completely, TankGuys.
Well, the wife just got home and made me turn on the heat in the house, so looks like no more good pushing of the chip tonight. I'll just try burning in at stock volts and keep nudging fro 2800 as high as it'll go. at 2820 now @ 1.32v.

thanks, I'm excited about it. I am gonna try to prime all night at 2.8 stock volts, and let my thermal paste settle in, or whatever, and see if that helps.
Absolute, didn't yours improve with burnin?
Yeah, i used to need 1.45v for 2.8 Ghz, and 1.6v on 2.95 Ghz would fail in a few minutes. Now 2.8 needs 1.42 and 2.95 runs fo rhours with 1.6v. I used to need 1.58 for 2.9, now i can do 1.56, or 1.53 if the room is cold. It's kinda weird. I'll keep trying to burn in, but no matter what i do or the volts, i can't do 3 Ghz.
Hey guy's, Iam new to this forum, I wondering I just bought a X2 3800
stepping is a LDBHE 0606 wondering if anyone has hit 3.0GHz or close to it.
and one more thing which DFI mobo should i get the ULTRA-D or SLi
thanks
not sure about the 0606's....not too many around. You will be very lucky to get to 3.0ghz without phase, but that doesn't mean that you can't.
and the mobo depends on if you want to use 1 or 2 video cards. 1 = ultra-d
2= sli....also, the ultra-d can be easily modded to the sli.
good luck with your new toy!
Well, I've run a T and an N from the same week. They clock about the same, just have different ways of getting there. Very different thermally.Quote:
