OCing 600E to 800....should I buy cas2 or cas3?

[SpaceBoy]

I am planning to overclock an Intel PIII Coppermine 600E up to 800mhz with my Asus P3B-F motherboard. I don't plan on using a peltier, just an Alpha P3125.

Which PC133 128mb stick should I buy?:

1. Mushkin Budget ($114)
-this cannot run at CAS 2
-the max for this stick is 146mhz Cas 3

2. Mushkin High Perf. Rev. 1.5 ($139)
-the max for this stick is 146mhz Cas 2

Since I'm overclocking, should I go with the Cas 2 stick? Is it worth the money? Is Cas 2 recommended for overclocking? Or will Cas 3 be just fine?

let me know.
thanks.

Get the cas 2, you won't regret it if you decide to push the envelope of FSB!

I am not sure how good the Mos v.1.5 are, but I know for $10 more ($149), you can get HSDRAM @ www.pc133memory.com

I have been able to run it @ 150 MHz 3-2-2 with Precharge on on a BF6. BTW, alot of this also depends on your mobo. Some RAM likes certain mobo better than others ... sometimes almost seems like luck of the draw if you ask me. Also one tip that was passed on to me from others and often over looked ... if you are having stability problems, try to put your RAM in the first DIMM slot, but I know the Alpha 3125 are kinda big and you will lose the 1st DIMM slot on the P3BF (I also have this mobo too) ... so I guess you gotta use DIMM 2 or find some way to get around this

Where did you see it for $140. I am stuck at 144 MHZ with my pc133 Micron cas2. and NigtOwl is about to whip up on me bigtime. I need to go faster fast...

PS. the HSDRAM cost $10 more at pc133memory than the Mos v1.5 @ Mushkin, but pc133memory include free shipping in US, so this might offset the cost ...

Thanks NiteOwl, I have been looking real hard at 128m HSDram. I think I go the site once a day, but I am tossed between the Muskin, and the HSDram. I need to S.O.G.O.T.P.

wow...lightning fast replies.

what's the difference between
HSDRAM and SDRAM?

Will HSDRAM run better at higher bus speeds?
(Compared to cas2 SDRAM)

I will definately look into the HSDRAM.
Thanks guys.

HSDRAM is SDRAM, but I think has faster clk access time 4.6 ns while normal SDRAM has clk access time around 5.4 ns ... but don't confuse clk access time and the speed at which the chips are rated for. HSDRAM has 7.5 ns chips. I think the Mos v.2 has 7 ns chips. The HSDRAM has had a reputation for running at high FSB for a long time now while the Mos v.2 RAM are new but are quickly making a reputation for themselves. I am going off to bed now ... this time for real! If anything, post here, I am sure one of the others or myself (next morning) will be more than willing to answer your questions to the best of our ability.

Im running my two cheap 128Mb Samsung PC100 cas3 sticks at a nice 148 MHz, i have never expierenced any problems.. nice bandwidth results in sisoft-sandra too

I`m currentlt running HSDRAM @ 135,2-2-2-5. It`s verry stable and well worth it.
