2700@1.69v (on bios) -> 53C full load on both cores with ~25C ambient and a Big Typhoon on a Stacker
Right now 2600@1.55v 47C folding on both cores.
I think the temps are pretty decent for the volts involved. But since I've seen my naked winnie 3500 indleing (low volts, low clock) at 3C below the ambient temperature I don't trust these readings.
stil testing my 4400+ x2 0534 spwm
so far so good i deed 1.71vcore to dis 1m pi run , cooling was wc .

but il have to stop testing for now unlit my x800GTO² comes and a good hdd.
p.s no tweaks ;) , i can run pi 8m @ 2.86ghz withe 1.63vcore :D
Cheap 165 Opteron's for socket 939 give those X2 4400+/4800+ really some decent :slapass:

just some some ice water oc'en on my 4400+ and it think 3gzh benching pi 1m wil be its max, vcore 1.75 , vdimm 3.6v :banana:

This one chip gets too hot to handle... have Big typhoon just about managing to keep it going... nop I don't plan to get IHS off. Any idea how to optimise cooling. Temps keep on fluctuating with 36-58. 58 is where I get a feeling of loosing X2 :mad: . But with India's HOT weather I think this is good result. Need to get a WC kit or make one by my self is possible. How safe is to run 2.9V thru OCZ Plat Rev 2 (TCC5)?? Have been eyeing "DDR600" for a while now so need to be sure as cant afford to loose anything. With 2.8V it gives a lot of Test 5 errors :slapass: .

my new X2 3800+
Stepping: CCBHE 0533 SPMW (never seen a ccbhe). On Watercooling. I think it's a Toledo core, maxCaseTemp detects it as one, although cpu-z says its manchester.

I am running on 2.67*10 for 24/7 max prime95 is 2.6ghz ,but 2670mhz run just fin
I am håp tweaking up to 2.7ghz +-
max bench (for now) 2mb and 4mb superpi and 01se stabil :D
2.9ghz x2 4400+
290*10 1.6vcore
I am pleased :D
I have a toledo based x2 3800 currently @2.5 1.475v
are theses temps ok?
41c idle
55c load
xp90 panaflo fan
do the toledo core versions of the x2 3800 run hotter than the manchesters?
whats a safe limit voltage wise?
thanks

How much voltage is too much for these toledo X2s?
My 4400 is running @ 2750 1.55vcore
-21c idle 0c loaded
I want to get 2900mhz but even 1.7vcore wouldnt stabilize it.
I'm running a divider of 150 also.
1.6v is looking to be a sweetspot for my cpu.
Currently Prime95 stable for just 2 hours...but I think before I was using 1.7v and that is just too much voltage.

2794mhz 1.60vcore
Load temps of 0c
Alright, after i finished my water block grinding and now have full contact with the cpu, i'm hitting the wall @ 2720, 1.52V and 50*. So far about 15 hrs prime stable, i'm going to lap my block (currently only 300 grit) try out a heater core to try and drop some temps, and then try another block with a thicker base.
I had to back the OC off to 2717mhz at 1.50vcore. I couldn't get 2794 stable for more than 2 hours. Average fail time was 20 minutes.
What kinda chipset and ldt voltage is everyone with a comparable overclock running? I bumped both up .1
Chipset reads 1.6v and LDT reads 1.28v
Anyone got a suggestion on how to get a higher stable OC...Right now my loaded temps never reach 0c. I can hit idle of -24c.
Tok the IHS of yesterday..
temp loss frome IHS on and air cooling to IHS off an watercooling is about 20c load..
Priming at 2720MHz @1.61v atm. On air with IHS 2600MHz was maks.

1.5v vcore, 1.4vLDT 1.6v chipset 2.8vmemory 24x7 stable at 255*11 = 2805 on a 4800 with the IHS removed under QUIET watercooling. CPU hits 39 deg c after priming overnight.
edit: oh, and C&Q working just fine for when i'm just surfing - drops to 1.2v vcore and 1275mhz when idle :)
I am using a 4800+ now and have that running stable at 3080 at low voltages with a 10x multi and 280 fsb.
I am using a Mach 2GT. I had a 57 but i screwed up with the seal and the chip got some moisture on it and it corroded the core :-(, I will put a photo up on the site soon. I had that running at 3.5 G and could bench at 3.45 voltage didn't work at getting higher clocks. I had no cold issue.
Ive clocked mine down to 2.4 with 1.3V she gets 47-48 dual folding and I dont like that..
Isnt that opt a dual core also? the 175 I mean..
Sweetness.
Currently 2838mhz 258x11 1.648vcore 1.6v chipset 1.47v ldt 2.62v ram.
I can run 32m super pi, OCCT, and PCMark05. I am going to prime overnight and see what happens.
259x11 2849mhz 1.680vcore 1.6v chipset 1.47v ldt 2.62v ram
SuperPI 32mb pass
OCCT pass-I tried to run SuperPI 32meg and OCCT at the same time. OCCT would fail 20 minutes in. (not a good sign me-thinks)
PCMark05 5510
Prime failed after 4h 50 minutes. I will test each core individually while I am at work.
I think I might bump up the voltage to 1.55x113%. See if I can't get totally stable that way. I am pretty pleaseed though. I will be testing out stability in 3dmark and games tonight.
Any advice would be great.
My advice.... probably to take the clocks back to 2.8 Ghz and lower the voltage. Even with those great temps, 1.7V is a lot to run 24/7 on a dual core. I would try to keep it at 1.65 and under.
I plan on backing off 100mhz and run at 1.536v. I have been going over my results and 100mhz just isn't worth it. I do want to find the highest stable clock for sh|ts & giggles.
Hi, im about to buy a 4800 X2 and would like to know what are the good steppings for OC with this CPU for now i have this one...
ADA4800DAA6CD CCBWE
0531WPMW 1312136H50227
Anybody know if this one is any good? and if not witch are the good steppings for the 4800 X2..
i think WPMW is normally a decent stepping. later weeks aren't to bad on these X2's (yet), i've had two 0533's that hit 2.7ghz with low volts.
What do you think i can get with WC with a Asus SLI Deluxe?
Bumped up my OC 290x10 1.696vcore divider of 140...28m 05s superpi 32m...Not priming for crap though. Passed OCCT also. Also got me a 3DMark05 score of 14026. This is running standard performance Mushkin at stock timings. This almost is only 43 points shy of my best score with my x2 4800.

hey bullit how long did it last at 1.6 i'm at 1.5 on a 4800 what kind of distance am i looking at weeks months or a year
