My 256MB Samsung PC2700 is running at DDR425 (2.5-3-3-7) :)

You can try setting the CPU/RAM ratio to 4:5 in the BIOS. I have my SAMSUNG PC2700 256MB running at DDR425 (2.5/3/3/6) on a P4B533-V. The latest BIOS (ver 1005) also let you use 3:4 ratio too. BTW my DDR voltage is 2.7

Asus has put the new BIOS for P4B533-V on their Taiwan ftp site. It's version 1004. Go get it !

I could go above170 to 176 FSB but I need more volt (1.7v in BIOS which is about 1.77v actual for ASUS). But the mobo will give me frquent beeps which I don't know what it means. I just guess that it's a warning of overvolting before I fry my CPU. So I settle with 170FSB (1.65v which is 1.728...

I have the actual beta 14 running. It does not give you the choice of ratios but actual DDR speeds which work out to be 1:1, 4:3, 3:4, and 4:5 The link is ftp://ftp.asus.com.tw/pub/ASUS/mb/sock478/p4b533-v/1004p4bv14.zip Go get it

I have just flashed the 1004 beta 14 BIOS dl from asus site on my P4B533-V. This version allows you to use 3:4 ratio above 133 FSB. So I am dancing my 1.6a at 170 FSB @1.65volt (AsusBIOS) and running my SAMSUNG 256 MB PC2700 at DDR453 with 2.85Vdimm. cas 2.5/3/3/6. Been running prime95 tortue...

I have a 1.6a @ 169 Mhz/1.675V, Mem ratio 4:5 Samsung 2700 DTL @2.85 V on a ASUS P4b533-V. When the temp gets to 56C the mobo start crazy beeping. I guess it's a warning that clock throttling has kicked in (verified by a sharp drop in benchmark score). I have seen of you guys quoting temp as...

ColdBrew: I have the same P4B533-V. When I set it to 1.75 volts it booted into windows OK but it gave me some crazy beeping continuosly as you have experience. I wonder what's that beeping for ? Can anyone shed some light into this ?

Thanks Thugsrook for the answer. I made a mistake on my post. The RAM setting should be 2.5/3/3/6 for 160 FSB and 2/3/3/5 for 182 FSB. BTW at DDR400 the cycle time for prime95 is 0.256, at 182/DDR384 the cycle time is 0.271 sec. This is quite contrary to your suggestion that 182 FSB gives...

Actually the one before this one managed to run prime 95 for hours @184 FSB @1.75 volt. I got greedy and fried it by pushing it to 188FSB (3008 MHz) @ 1.775. It ran stable for a while then it gave me windows protection error at boot time at all speed. So I RMA it and got this one which is a...

Both settings run prime95 for hours without crashing.

182FSB @1.725V tem 54C mobo temp 32C I let 160FSB sit @1.7V temp 52C mobo temp 32C. I have not tried lowering voltage for 160FSb. I think it can be lower.

I have a 1.6A which can run stable @160FSB ratio 4:5 2/3/3/5 and also 182FSB ratio 1:1 2.5/3/3/6 on a P4B533-V with Samsung PC2700 256 MB single side module. Which setting should I use ?

I have a boxed Celery 900 Q201A564/SL633 running at 9x150@1.85 Volts on a BXMaster. I removed the fan from the retail HSF and screwed a Delta 5000 rpm on it. It's absolutely stable. VGA is G400 which has no prob with 100 MHz AGP bus. I might also add that this stepping is not even listed...
