EDITED. I'm looking to setup a new Sempron 64 machine for a friend and saw 3 different steppings out there. E3 and E6 for boxed. My question is which one is better at OCing since I'm planning on pushing it with a nforce 3 board . Thanks.

UPDATED 1-27-2006

Wanna give a big thanks for all who posted help here, love ya all. Here's what I ended up getting.

With my limited budget I got a E6 2800+, vnf3-250 total 130 bucks from ZZF. Got an Antec 1650B for case. Flash vnf3 to v6 BIOS, no vcore adj. MBM shows 38C idle/ 51C at 100% load. So far at default vcore 8x300=2.4, 3xHHT (900), rest APG/PCI locked at defaults. Running DDR400 with 2/3 divider. Prime95//2hrs+SuperPi 32M//30min+OCCT//2hrs stable. Still doing more stability testing right now. Seems faily alright. I don't think the vnf3 will stable higher than 300 clock - this is probably the bottleneck of the OC.

Seem to come close to a 2.2 Venice in most quick benches but can't beat it in games. But no matter only using a 6600GT for games for now so it's the bottleneck in gamez. The reason I didn't go for opteron 144/6 with nforce4 board is that I got too much legacy stuff AGP//PATA etc and short on cash. Gonna get a new setup entirely when M2 comes out with a dual core X2 // DDR2 // PCI-e g-card etc.

I've heard alot of good things about the DFI NF3 Lanparty's and MSI NF3 Neo's...I'm happy with my VNF3-250 as it only cost $54!!!!

I got the abit NF8-V motherboard at fry's and have my sempron 64 2800 @ (2.0ghz) the board runs it nice and stable to. I haven't had one lock up with my machine at all... all I need to get a new graphics card now... ATI has compatibility problems with one of my games. The one I play the most TO. And I was able to get my sempron at 2.0ghz with low-end Mushkin DDR-400 ram... ALL in ALL a decent board

I already have an OCd Semp. Just want a board that has bus settings up to 350 or so, and full Voltage adjustments.

I'm looking at this board. Any comments? Nice combo with the Semp 2800+.

The Semp 2600+ I have does 250bus (the boards max) at 1.4V (stock). Dying to try one full out with a better mobo!!

That board is the one I wanted when I wanted to build my system originally but I wasn't able to get the board... I say go for it the Biostar has some of the best-intergrated graphics around. Has PCI-e for future upgrades. I would have to say that would be a good board for a little sempy-based system...

Agree, it's a very strong overclocker...

You can enable vcore adjustments on the vnf3-250 by flashing to an older BIOS.

I realize that an older Bios will offer vcore adjustments, but I got lucky and wound up with a 2500 that will run at 2334Mhz without having the adjustment. I really don't intend on overclocking any higher, since that is a 67% gain in speed. I already had to buy a bios chip for this board after a flash went bad, so I think I'll just leave it as it is.

Good plan. I flashed mine to an old BIOS and wound up not bumping the vcore anywhere, so it was a wasted flash. However, the old BIOS works well, so I'm sticking with it.

nyker96 -

Please edit your original post and include at least one link to the "E8" stepping.

Thanks.

DFI NF4X Infinity board if you're looking for a s754 mobo with PCI-E support. Not a bad overclocker either, i can do 2.5Ghz on my 2800+ sempron64 easily.

Tx for all replies. Sorry didn't check this thread for a few days. I was wrong about the E8, check some sites, they are all E6. Sorry about that. Correcting the thread title in a sec. Anyways, I just placed an order on VNF3-250 and sempy 64 2800+ E6. VNF3 seems to have a nice few OCing options. But I do plan to bump vcore up which I almost always do with OCing. Can anyone pass me some info as to where to get this older BIOS version to flash it? And also I don't see a BIOS flash utils on Chaintech web site. It might be hiding somewhere but any1 have a link I'd appreciate it. Planning to OC to 2.4/5 if the chip can take it. Using the stock HSF first then if I need buying a good HSF later to boost my OC as needed.

You can check here : http://forums.pcper.com/forumdisplay.php?f=46 . They have plenty of info concerning the bioses, overclocking, etc. Here is a direct link to Chaintech's site with all the bioses : http://www.chaintech.com.tw/tw/eng/Download/dl_desc.asp?DCSNo=4&PISNo=276 . Here is the flash utility : http://www.chaintech.com.tw/tw/eng/Download/dl_LI.asp?DISNo=704 . If you want vcore adjustments and proper memory recognition, I believe you would either need the 2004/10/19 bios or the 2004/09/21 one.

It may be possible to achieve 2.4GHz at DEFAULT vcore with your E6 Sempy. My E6 2500+ (1.4GHz stock frequency) has hit 2296MHz (7 x 328MHz) at default vcore on a VNF3-250, but I didn't prime it there (but did run Sandra). MY Sempy might go even higher at default but I'm running budget memory (one 512MB stick of Nanya PC3200) and don't particularly like doing OS re-loads, so 2296MHz is about as high as I'm willing to attempt.

Highly recommend you see how high you can get, frequency-wise, at default Vcore, running stability tests along the way, BEFORE increasing Vcore since there is at least one report in the forums of a Sempy dying at 1.5Vcore.

And you may well want to consider putting a fan on the heatsink on the nVidia mainboard chip since you will have to run the board at 300MHz just to obtain your minimum objective of 2.4GHz.

For costing almost twice what the Chaintech costs, it better clock 2x the overclock that the Chaintech is capable of. Oh wait, it can't.

Seriously I know that the board overclocks well, but gosh darn it is expensive. At that point you may as well spend the extra $50 on a faster CPU than on a "better" board.

The Chaintech is pretty good for a cheap board. I've also had a bit better luck with my Epox 8KDA3I board than my Chaintech, but the Epox board also cost $10 more. It does give vcore with a fairly new BIOS (if not newest), FWIW.

(I've got both boards and a Sempron 2600+)

Given that M2 is coming, which will push down the price of both socket 754 and 939, currently why would one buy ANYTHING that is AMD and even REMOTELY expensive unless one's processing requirements suddenly escalate sharply and dictate that one must significantly upgrade immediately.

I recently did my standard 5-year upgrade (I just surf the net using a cable modem and my Celeron 600 @ 900MHz finally couldn't keep up with all the active X, flash ads, etc. that use MY processor for THEIR advertising). Since I already had an ATX 12V power supply and a GeForce2 MX (from the Celeron PC), and 512MB of PC3200 from my initial, but later discarded plan of upgrading to a used Athlon XP and Socket A board, I was able to obtain both crispness on the www AND 64-bit computing capabililty very cheaply via Sempron E6 and the Chaintech VNF3-250 board. My research showed that processing-power-wise, Sempron 754 was a clear winner compared to Athlon XP Socket A/462 and could be done as cheaply or more cheaply since the components needed for either upgrade (motherboard, processor, and memory) were identical (if I were to continue using AGP) and Socket 754 had existed long enough for the prices for used boards to get cheap (the coming of 939 helped that process as well). Plus, via S754 A64 processors, socket 754 has a lot more "head room" than Athlon XP. No-brainer.

The beauty of the Sempron E6/Chaintech combo is that if the advertising on web pages (including AnandTech) gets even more demanding on my processor, I'll just clock it higher.

AMD is already marketing Socket 939 Semprons in Europe according to XbitLabs. My impression (which may be wrong since I haven't "dug into" 939 boards) is that 939 boards cost more than 754s. Certainly the processors do. And AMD isn't likely to strongly discount a fresh product such as 939 Sempron unless the competition with Intel demands it. So S754 Semprons should remain as the value bang-for-buck processor until they are discontinued.

Thus near to intermediate term, IMHO budget 754 boards with OC capabilities and Sempron 754 processors with E3 or E6 cores look like the way to go for apps that aren't seriously demanding. And since they overclock in to full-fledged A64 teritory, that is yet another nicety

Lastly, a relatively unnoticed benefit of the Semprons with E6 cores is their low power requirements.

I'd go with DFI just they cost a ton. Just got my vnf3-250. running a 2800+ 1.6 @ 2.4 stock voltage+cooler. decent 50% OC.

Congratulations nyker96. Have you tested for stability at that frequency?

Congrats, Nyker! Sounds like a nice lil' rig so far!

I've never messed with those Chaintechs, but I've heard they can O/C pretty well. A bios where you can't even adjust the vcore? And I thought my Biostar M7NCG -400 nF2 (HTPC) was primitive! But hey, if it works, that's all that counts!

You get spoiled with a DFI bios - you change everything but the color of the board!
