prescott ID and ram

hi'
with a prescott, which one is the best E0 or D0?

and one more question, it's written on my mb booklet that it support ddr ram from pc2700 until pc3200 which I have in dual ram 2x512mo,
is there any ddr over pc3200?
if yes, would my mb support it?

so ... after some search found some PC4400 ...
same question mb gigabyte 8iPE1000

i686

As for whether to get E0 or D0, I dontthink you have much choise. If am not mistaken, all 478pin chips are D0 stepping at the highest, and all 775 'pin' chips are E0. If there are 478 pin E0 chips, then get it because all of the E0's that I have seen overclock better than all of the D0's I've seen.

If you are thinking about using your gigabyte mobo in your sig, make sure it supports a prescott. Prescotts can kill old mobo's since they cant handle the heat and power draw of a prescott. If you find you need to get a new mobo, go for one with the LGA775 socket so you can get a E0. Also get one that supports ddr2.

As for memory support, with your current mobo there is no limit to the speed of the memory that you can put in the slots but they will only go as fast as the mobo tells it to go. A good idea would be to get some ddr500 (aka pc4000). When you overclock your processor, your memory will be overclocked as well. Using ddr500 and letting the mobo treat it like drr400 gives you plenty of headroom to overclock your processor without worrying if your memory is holding your clockspeeds down.

You can tell by the sSpec what core the CPU uses. The E0 is far superior to the D0.

Any ram 3200 or faster will work with that CPU/MB. It just not 'offically supported'

Fishy, are there any 478pin E0's?

Edit: might have answered my own question.

I think there are 478pin E0's. Its just been a while since I last looked into buying one and back then there weren't any 478 E0's while all the 775's were E0's.

Thanks fishy.

hi'
thanks a lot all
I have all answers I wanted, so for ram is like in the ol' time put a ddr500 in a slot for ddr400 is ok, just work like a ddr400, but comfortable for OC I like this
and for P4, I can confirm E0 for 478 exists, just have to find them, so have to ask online if they have this "ID" in stock, I have seen a P4E 3.2
ref:BX80546PG3200E and then arrive the sepc, 2 of them, the SL7E5 in D0,
and the SL88K in E0, one is supposed to be boxed with a fan, the E0, the other one no info
they are both in 478.

so, anyway, my mb support prescott until 3.4ghz, so it is fine with a 3.2
and I will add a XP 90 with a good fan on pushing a good cfm
or may be a 120 is better?
and for sure will add a 90mm fan on side of the box to bring some fresh air in, and might be one more on the top to exaust the hot air.

The xp 120 is better if you have the space for it. Also consider the xp90 copper. If you are going to add a fan on the side, construct a duct such that all the fresh air makes its way to your cpu and nothing but fresh air makes its way to your cpu. That is the single cheapest most effective thing you can do for your cooling after you get a good heatsink.

Good luck.

hi'
big thanks
I have seen the spec of the P4 I have now : "made in china" ...
Number of processors in system: 1
Current processor: #1
Processor Name: Intel(R) Pentium(R) 4 CPU 2.60C GHz
Type: 0
Family: F
Model: 2
Stepping: 9

L1 Trace Cache: 12 Kµops
L1 Data Cache: 8 KB

Intel(R) Extended Memory 64 Technology: No
Expected Processor Frequency: 2.60 GHz
Reported Processor Frequency: 2.60 GHz
Expected System Bus Frequency: 800 MHz
Reported System Bus Frequency: 800 MHz

so, seing this, I really thought it's time to improve the overall a bit
change already the video card for a gf6600 and sound card for an audigy2,
next step is new proc with good cooling, I'll look if I can put an SI120, if not I'll go for a XP90cu with a panaflo on.
if I get some money left after all this, I'll look for ram ddr500, and then OC will begin, just to bring it up to 3.6 and this will be nice enough for a couple of years

I know that many would say "go for 775" and the rest ...
the only problem is financial

I have to do with what I can allocate to the main rig, the ol' one is a PIII running Linux
