Sounds like phase to me.

That is on air. I had no issue getting our 955EE to run on air at 4.63GHz (1.39V,61c load,benchmark stable) on the Biostar board after the last bios update, which incidently will take the 950D to the 4.7GHz range without an issue.

We did preview the series here - http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2578

I do have a board under $100 running our new 950D at 4.8GHz in testing right now. ;)

interesting ;) make sure you do proper TDW testing and some idle/load temps :)


I don't know if it's that interesting..Don't let high numbers fool you -they are very ineffcient ones.. every 100Mhz you bump a X2 up 175Mhz is needed on a presler to keep up due to AMD's K8 architecture delivers quite a bit more performance per clock. So lets be generous here and say 940 = 3800+ or 3.2 Ghz Presler = 2.0 Ghz X2

Moving the 3800+ up 800Mhz to 2800Mhz you have to move the 3.2 presler to 4.6 to maintian some parity.


Same thing goes for Yonah. at 2.8Ghz Yonah would snack on any presler below 4.5Ghz.

I personally find low power 3Ghz Yonah and X2 overclocks much more interesting.:) The X2's more so because of inexpensive chips and inexpensive boards.

actually i thought it'd be interesting to see how much heat and power a 4.8ghz presler outputs. 300w? 350w? 400w???

need conroe NOW!

i think the whole "premium" motherboard and premium computer part theory that people put out is prettty stupid as it is.

there are tons of boards in the $60 range even that overclock just fine. the chaintecn nf4 ultra for example, get rebadged a bfg for twice the price and people seem to actually think the bfg one is better.

i mean the chipset is the same, and pcb and wiring etc cannot be much different. asus makes money on premium crap off fools.


anyhow i think preseler is a pretty good chip actually. the higher end ones with some of the dual core chips are actually decent at gaming too. i actually have the even more hated smithfield (it was like $150 and the 820 is not very hot running anyway) and well it seems fine as well, though im not a hard core gamer and i dont overclock.


amd has always been the underdog and most of these boards tend to support it. intel i think will be back, they were quite popular during the northwood 1.6A days.

But which is more likely to happen? A 2800mhz X2 3800+ overclock, or a 940D 4.6ghz overclock? I'd wager on the Presler. Granted, you're paying much more for the 940 than the 3800+.

well you could always buy a 930 or 920. the cheapest you can get with the x2 is a 3800... so it sort of limits you getting anything cheaper.

you should be able to get a 920 for $220 soon, seeing as 820s are going for $170 used.

Show me how many 165 and 170s you see hitting 2.9+ stable on REASONABLE voltage.

You won't see many.

Most chips slide in between 2.5 and 2.7

I'm really looking forward to finding out what this motherboard is, I have tried 6 diffearnt motherboards in the $100 price range, and none of them can overclock a presler past 3.7ghz. The P5LD2-VM was the only one I could get to 3.7ghz with, but I had to overclock the PCIe bus to do it, and the onboard graphics went completly out of wack. Most of the boards toppped out between 220mhz to 228mhz FSB before they would stop posting.

All the boards I have tried...
Asus P5LD2-VM-3.7ghz with overclocked PCIe bus, then one of my cores died..
Asus P5P800-SE 3.43ghz but again, can run higher FSB with single core
Gigabyte 8N-SLI topped out at 229mhz FSB 3.2ghz, but runs 245mhz FSB fine with my single core P4.
Foxconn 945chipset board..3.16ghz
ECS 945P-A 3.16ghz
Asrock 775-dual 880pro(no vcore options) overclocking worked backewards..(yes it lowered CPU speed..but overclocked normaly with my single core P4)

Do you read anandtechs motherboard roundups at all? Things like power regulation, crosstalk, layout, features, and even the quality of the capacitors can effect performance and overclocking.

Theres a massive difference between a $60 motherboard and a $150 in some cases. Read reviews and do research and judge for yourself whether its worth the money.

none of those affect performance. the only thing some of the better boards have is better ram timings and bios tweaks etc but that really has nothing to do with capacitors or whtaever. most of the boards are 85% built off an intel reference design as it is.

power regulation may affect the absolute peak overclock obviously if they overheat when you have the clocks set super high. but then again who cares. it is pretty stupid to spend another $90 for a board, just so you can get maybe 200 mhz more out of a chip. they dont give you a medal for getitng the highest o/c. i thought the point of o/cing was to get more performance for your money, i'm just saying a $60 board probably will still have some overclocking features (or you could probably find a board that has some). sure you wont get on the hardocp front page, but seriously now you are saving $90.

Presler runs a lot cooler than smithfield, but so far there has been no luck overclocking to 4ghz on anything other than the $200 P5WD2..4ghz is where it will start to surpass a 3800+ X2 oc'd to 2.6ghz..IF somebody can get it to OC to 4ghz on an inexpensive motherboard, then it will be the best bang for the buck. So far, with 4 differant motherboards, the highest I have gotten mine is 3.7ghz, where it just barely starts to catch up to my X2 @2.618ghz.


Why go cheap on a mobo anyways? makes no sense to me.

I went pretty cheap on a mobo. I guess thats why. Whats the point on saving the money on the cpu if you are going to blow it on the mobo and ram to overclock.

Cheaper to get a good mobo than the higher clocked CPU's.

ASUS P5WD2-E Premium Socket T @225.00 + P920 @258.00 = 483.00

beats the crap out of:

ASUS P5LD2 Deluxe Socket T @ 152.00 + P950 @ 663.00 = 815.00

So, that's the point ;)
