[Official]- Disappointed with the Athalon II X4 640
I got some detailed directions from another member on here for my board specifically so I'll give his stuff a try but I'm not exactly holding my breath. I again think that boards not CPUs are limiting in getting beyond the 250 reference clock thing as I've heard about it as the wall for 4 plus years in the AMD world.

I think that thread would compete with the "Dissapointed with the i7 930 (or is it 940)" thread. I saw a lot of people a month or two back when I was digging around the intel section complaining about that after the 920 got replaced the quality of its replacement went down for OCing. Coincidence...I think not.

All in all when I think of just how much things have changed in 4 years I don't feel too bad about the CPU(the mobo I'm still a little angry about). I remember shelling 125 for my old 6400windsor that no one on earth could OC more than .2GHz. And then 250 for my Q6700 which did 3.1GHz below it's VID since I bought a cheap ECS G31 board with no voltage control that decided the VID of 1.35 (iirc) was too high.

I also think about snagging a 955 I've seen in the FS section but I just think "if I'm struggling and disappointed now, imagine how disheartened I'd be if I can't even get that thing past 3.5". Also, considering what I've read around here my mobo is not good enough for OCing a 125Watt CPU. For that I'm supposed to have a 6+2 phase or something more than a 4pin CPU power pin.

I'll report back how I fair with the more direct info I got.

I look forward to seeing what you get.

I went from an old X2 5900+ I was able to OC to about the same place on the asus M2ne-sli. I built a work computer with a 955 a while back and it never occurred to me to OC the thing. I Spent 1800.00 on a Firepro video card and I guess that was the majority of my focus for that rig, oh yea and working on it. I had heard about Ocing at that point but didn't really care like I do now.

Actually I think the last of the "handicapped" Phenom IIs were discontinued before the 640s came out as a way of preventing too many people doing that. I think they are entirely pure blood Propus chips now which mean they never had an L3 to begin with.

But part of me does think that AMD might have pulled an Intel with these considering what I've been reading about the performance compared to the Phenom IIs. I saw many reviews show that when a Phenom was brought down to the same clocks it would beat the Athlons all the time but when the Athlons were clocked up they were within a 2-1% loss and on quite a few occasions even. So making these chips cheaper and risking the loss of Phenom sales I think they rightfully (from a business viewpoint) might have gone with cutting inter-chip competition by reducing the OCing potential. Of course I can't rule out that this might be a mobo or RAM problem instead but it makes sense.

Tried about four different settings and 3.75 was not working. I went up to 1.525 or so on the core and 1.2325 or so on the VDDNB(one more + and it's yellow) while trying out 2.5 and 2.25 GHz for the NB all to no avail. The system did seem strangely better at these settings than when I had the VDDNB up at 1.38 but this might be due to the (hopefully) correct LLC setting I've been using this time around. If I can't get 3.6GHz stable at 1.5 upto 1.525 then I may start considering trying other tweaking goals. First I might see how low I can go voltage wise for stocks. Second I might drop the cpu mult and look for the highest ref clock I can get while being at or above the stock 3GHz speed. Finally, I might sell the Athlon and snag (if it's still available) the 955BE floating around in the market place.

@Cook: You have 4GBs of RAM right? When you boot up and it displays the RAM amount to you get two different results between the ok and installed numbers? IE: I get a result that states "4095MB OK (4096MB installed)".
I want to rule out RAM being bad but I have no clue how. The last time I got bad RAM the stick wouldn't let the system boot so I knew then.

In all for a ~400 total build the stock results still beat the crap out of every game I play except Crysis. DMC4, UT3, Assasins Creed, Dead Space, all maxed out at 1920x1080 and maybe the occasional slowed. Considering that I couldn't truly max any out with my laptop or the last desktop I owned I'd say I got what I paid for.

But still, I'm part of OCN and we're never happy leaving well enough alone are we?

Be back either today or tomorrow with the 3.6GHz attempts. Wish me luck.

I do currently have 4Gb of ram and mine shows the full 4096 as useable. I wouldn't think the 1Mb would make much of a difference as it could have been a rounding issue, especially considering My 16Gb flash card only has 15388Mb of storage and my 750Gb Hdd has 767 Gb of storage. Memory and storage seems to be a "good enough" product.

You can stress test just your ram with memtest and a few others, but I would set everything to stock and test one stick at a time by removing the other before doing that just to isolate.

I am going to go for the 8gb Rip jaw set 2x4gb as the voltages are lower and they are cas8. Most people have been having great results with them and I want to start sticking stuff in my rig people are having good results with. I am with you on picking up a 955Be, a guy on CL has a 965be he just replaced with a 1090t for $60.00. I will be picking that up if and when he contacts me back.

How long do you think I should run memtest for? It told me to exit after one pass with no errors (but it did list only 4093MB or RAM). Actually, I think I'll go p95 on defaults and see if I get the out of sync cores followed by a BSOD. Maybe something's wrong with everything?

I think there is enough supporting evidence from you issues, mine and everyone else who has chimed in on this blog or who has posted during the last week to conclude that the AMD Athalon II X4 640 true Propus with the C3 stepping is the Lowest common denominator and should be blamed for all the worlds economic, catastrophic, cultural problems. I am an extremist it seems.

LOL. You call that extreme? I want to have Vlad the impaler resurrected so he can oversee the impalments of everyone who created and supplies DRM. I just found out that my legit copy of Riddick will not work (it's only my second install too).

So compared to realizing that I wasted 30+USD on a game I can no longer play I'd say that the lack of OCing excellence has taken a back seat in my rage list priority.

Got stock stable at 1.3v so it's interesting how the VID was 1.35. I will start working the hard way to find my limits with this board.

What are you end results for the OCing?

Hello! I also didnt any reserch about the 640 and now I'am stuck... got i to 3.4ghz and then i noticed i didnt have the latest bios and upgraded. well thats a mistake and now I cant get it to overclock at all. I have the asus m4a88t-m with llc so if I put my vcore to 1.39V i wiggles about 1.36 to 1.42 even 1.44 some times. and thats dont feel right at all! system becomes unstable about 20-30min in prime95 little worried about the temps aswell, if i put the vcore up to 1.4v the cpu gets to 61 celsius in load but the core goes to 50 celsius sometimes but not above. when the cpu comes close to 62 it sets the multplier to 4? havent seen that before. well if somebody knows what to do please respond and sorry for stealling your thread! but really got fed up with this crap and dont know what to blame, cpu or the motherboard, or the memory maybe? have kingston hyperx blu 1333mhz if thats help!

Edit: Uses artic cooler freezer extreme and thought it would do god, even tried to reaply the mx2 thermal paste 2 times but doesent help with the temps.
