Will buffalo PC3200 512mb (Winbond CH5) be able to handle 5:4 memory ratio?

If not, what <$100 ram will?

Depends at what FSB. Typically, the 865/875 has problems with 5:4 CH5 at over 255FSB.

The cpu will be a Pentium 4 2.6C on a Abit IC7 board. If it can handle 250MHZ rock stable, thats good "enough" for me.

 

[Lyfer]

anyone?

if 250 is your limit you MAY be ok, but I would still not recomend it considering you will want more when you get 250 stable. Then you go for more and the ch-5 bug kicks in. try to find some bh-5 or maybe the hynix chips that play a little better with dividers. For some reason 865/875 chipsets just dont agree with them and its best just to stay clear of ch-5


This is from my experience others may vary 🙂 🙂 🙂
And how much ram are you lookin for for undr $100

I don't want to pay more than $110 per stick of 512mb, plan on getting 1gb. Kingston's having pretty good deals on Hyper-X PC3200, is this stuff any good at 5:4 ratios?

KHX3200/512 This version is good BH-5
KHX3200A/512 this one is bad ch-5
If it doesnt give you one of those exact part numbers look at the timmings

2-2-2-6 = bh-5
2-3-2-6 = ch-5

this is for the kingston hyperx only, and it looks like the bh-5 ones are $12 more at newegg than the ch-5 ones

$122 x 2 sticks and sales tax, ouch, outta my budget. Will the buffalo with Winbond chips be able to run 250MHZ stable at all with 5:4 dividers? If it can, I'm sold unless there something out there that is <$110 and can.

I was able to hit 260fsb with a 5:4 divider with my 2.4C and P4P800, this was with one stick of PC3200 CH5 and one stick of HyperX PC3500. To get it stable, I had to run craptacular timings of 3-4-4-8. With my new Mushkin PC3500 Level II BH5, I can hit 272fsb at 5:4 with 2-3-2-6 timings. It's a gamble, but I believe 250fsb is achievable with CH5, though at poor timings.

260MHZ FSB with CH5, thats exactly what I'm looking for, not really interested about aggressive timings (this is budget ram).

Try and find Buffalo PC3700 using Winbond BH-5. Price should be about $100.

It does 250 (5:4) at 2,2,2,5 with no problems.

Shameless plug

I got up to 275FSB 5:4 with GeIL PC3200. Don't be afraid to give it more voltage.

I used to run TwinMOS CH5, I couldn't get past 255FSB.

I had minor stability issues (ie infrequent rebooting) with a 2.4C @ 3 GHz using a 250MHz FSB and a 5/4 dividor and CH5 RAM (Twinmos PC3200), and at anyting above 250 MHz it couldn't even make it into Windows. I wouldn't gamble with CH5 on an 865/875 chipset. Once I got BH-5 I could o/c to 3.15 GHz with ease.
