Anybody got one of those 2400+ chips running yet!!!

Where are the reports?? I have heard a couple ppl now say they ordered one and it was not backordered plus one guy say he had it.....

Looks like the supply is improving, anyway. You-know-where has them for $199 now. I still don't see them at MWave or Axiontech yet, but strangely enough, TechStore.com lists the retail-boxed version for $204, but out of stock... might be one to keep an eye on. Sorry I can't set foot on that slippery slope for you guys... :(

Ya, I had mine delivered earlier tonight.. AXDA core.. Gonna put the box together this weekend and I'll let you know how it goes. Hopefully she's a good OC'er *crosses fingers*.

I installed mine saturday and have been disappointed with my overclocking results. I unlocked it using this method and it allowed multipliers 6.0 thru 12.5. No matter what combination I try, I cannot get it stable past 2120 MHz. I was able to run 3dMark at 2.2 GHz, but it would crash immediately with Prime95. I am limited by my motherboard, an MSI KT3 Ultra ARU, because the vcore can be increased only to 1.75v. I feel that it could go higher with more juice, but I am not sure how much.

I did break 14,000 with 3dMark, so it isn't all bad. I am still very disappointed though because I was seeing results of others at 2.3 and up.

Cool, what kind of heatsink do you have lined up for it? :D edit: errr, that question was aimed at Ravho, but hopefully everyone will elaborate on their cooling setups?

I have a Thermalright AX-7 with an 80mm Enermax adjustable fan that is spinning at max of 3515 rpm. Oh, and ASII as the grease.

SK, what about joining the voltage bridges to boost the voltage? Here's a nifty guide that shows what bridges to modifiy to get your desired effect.

I am a bit confused by that. Does it mean that if I connect the L11s, I am locked at that particular voltage (1.85)?

I think that's just the default voltage that the CPU requests from the motherboard. How about 1.80V for starters?

SK and MechBgon, reresh my memory but what were the vcores the reviewers were running when they were getting 2.4ghz ocs??? I think Toms talked about exoctic cooling so I can assume probably higher then 1.8v....Does the .13micron application of the AMD not do the damage as the INtel p4's or is this too soon to tell???

The .13 tbreds are 1.6v right??? Therefore like the p4's about .2v is about as far as one may want to go to not start the effects of electromigration and damage the gates....

I remember early northwood ocers with water cooling and wire modding were hiting 1.9v in some of the super high ocs...MOst of those at other sites I heard went along the wayside or the use smarted up and backed her down.

I know that the board can be volt-modded, but I have never used a solder iron, so I am a little scared of that!

1.65v...Hmmm...I wonder why amd's vcore for the .13micron is A) higher then Intels by a bit, and B) only a .1v drop from the .18micron chip....

Is it architecture that dictates this?? At 1.65v most p4 owners don't go much past that....

Is this a sign the AMD chips are actually volted too high and may show that they will be short lived and limited in ramping???

I wonder if they perfect the process a bit more they will reduce it a bit more....

NOne of the reviewers obviously ran the oc'd chips at those speeds long enough to see if there was detrimental effects to the gates of the chips...It took like a week at over 1.83v to damage my chip..never killed it...just knocked it down a bit...

Good point, guys, I had Palomino on the brain here :eek: Here's what sandpile.org lists for the Tbred 2GHz:
2000B MHz TH CPUID=681: 59.3 W (1.60 V)
2000B MHz TH CPUID=681: 62.0 W (1.65 V)
So there may be some of each out there? Anyway, I would want to stick within 10% of the intended voltage... maybe that's a little conservative, but $200 CPUs are not worth risking for another 200 3DMarks payoff.

I checked about 4 diffrent sites and they all seem to reference 1.65v.....

Tomshardware had its 2600+ up to 2.66ghz at 2.2v (OUCH!!!) cooled with expensive watercooling setup...I bet this would be dead in no time!!!!

Hardocp.com had his 2400+ UP TO 2.4GHZ tested for stability for one hour but was only using 1.85v of vcore and running better then average air cooling....


At 10% mechbgon I think you would only be looking at 1.8v tops....

So hopefully the chips the reviewers got weren't just best hand picked chips and the majority of 2400+ can do around 2.4ghz with around 1.8v as that would make it around 2800+...ONly time will tell how well they will last being the smaller the size (ie .13micron) the more delicate the parts. I am thinking 1.8-1.85v will be like p4 users around 1.7v...may last 1 year or so...jury is still out on that one...mine is doing good after 4 months now...actually did some tweaking and got my 1.6@2.752ghz w/ 1.71v prime stable for 5 hours...I think the memory timings may be very pciky with the epox mobos....

amd processors are able to handle higher vcores a lot better than Intels. Many people here are running their 1600's at 1.8v-1.9v with air cooling.

Yeah, but comparing a .18µ cpu to a .13µ is not valid.

Exactly so I want to know why the amd chips are higher vcore on the .13micron process and if ppl go much past 1.8v like intel p4's will look at certain doom!!!

1.8v t0 1.9v on amd .18micron is the wrong comparison...willamettes will do those vcores....

Yeah my first thought was that the .13 chips wouldn't be able to handle as high of a vcore
i thought they would fry at a lower vcore
but this don't seem to be the case
i've read across a few forums where people are running them over 2 volts

this don't mean that the life of the processors isn't severely limited
we'll see how many people come crying in a few months
i guess amd did some good improvements with the new T-bred core
that extra layer might be attributed to the increased ability to put up with the high voltage

but the cooling will become even more important

I have mine running @ 1.75v and after 14 hours of prime95 the highest cpu temp I saw was 41C. I can't help but think this chip could take another .10v and handle it reasonably well. Then again, I know practically nothing about chip design, tolerances, etc.

Temps are a concern but when it come to voltage to high of voltage for a short time even without high temps can damage...

My p4 1.8@2.52ghz with 1.83v lasted there for over a week...prime tested it once for 24hours rock solid...temps never went over 52c for load which is considered good since throttling doesn't really kick in until 66-70c. It then ran mostly idle at 39c for the rest of the week. I then tried to encode a few divx movies and then it happened. I developed an error, then when I tried to boot into windows xp it wouldn't let me. I had to drop vcore to 1.7v and 2.4ghz to get into windows and everything was good again....until another week then 2.4ghz wouldn't hold...same errors...Finally it settled down at 1.8@2.25 w/ 1.58v where it ran happily for 10 weeks until I retired her.

I likely damaged a few of the gates and when it came time to use them in mostly the apps that really load the cpu it would error out.


ONly time and the first bunch of users as guinea pigs will find out the true limit....


Many guys though as long as temps were fine with p4 they were fine...had watercooling units and 1.85v plus and slowly a bunch of those started dieing off even though most never saw load temps higher then my system temps!!!

I guess prudence calls for a wait-and-see attitude here. For now I will settle for fast and and hold off on d@mned fast.

Yes definitely keep us informed on the stability of the overclock of the 2400+ as you are one of the first around here to have it....

I bought one today. Should be here by Friday night. I will install it about, oh, let's say maybe 20 seconds after I pick it up off of the door mat. O.K.? :) I will post on this thread if you are interested. It is going into PimpDaddy below. Current benches in thread "SOYO KT-400 worth the wait? Motherboards forum.

I got mine today, runs ~40 degrees cooler than my 2200+. I haven't tried overclocking it. I have question though, is my CPU automatically unlocked - Can I just select any multiplier on my A7V333? Thanks
