MOBO + CPU question? 1

[alildevil]

Planning on a new Machine but came up with 2 Questions hope someone can answer me.

On this page I noticed about the CPU

http://indigo.intel.com/compare_cpu/...ultu

re=en-US

I see that the P4 3.46 Pentium® Processor Extreme Edition 955 and it has listed under it:
Memory Type -- Dual Channel DDR2 400/533
------------------------------------------
I will be using a ASUS MoBo (P5WD2-E Premium) and it supports 4 x 240-pin DIMM sockets support max. 8GB DDR2 800/ 667/ 533 ECC and non-ECC memory.

http://usa.asus.com/products4.aspx?m...l2=11&l3

=248


Question 1. I plan on using some 800MHz Ram will that cause any problems with the Mobo and CPU Combo, seeing how the MoBo has that listing of 400/533???

Question 2. Also the Asus MoBo said it supports 1MB L2 cache and the CPU has 2x2M L2 cache, Will this also cause any problem?

I would appreciate any help with this the reason is that I have to order these 2 parts very soon. Along with a few other things.

Also the Asus MoBo said it supports 1MB L2 cache

I think you misread this, as I read it as pertaining to support for the single core with these specs. Next was reference to the dual core support.
The ASUS brd states support for 05B/ 05A and 04B/04A Intel processors.

As this cache is on chip, the board really does not interface at this level. In short, this mobo supports the dual core proc & the cache on chip.

Your link to Intel did not work so I did not see where you were concerned about RAM Speed. RAM is off the CPU chip and ASUS mobo supports DDR-2/800. So there should be no concern here.

If you opt for DDR2/600 mem watch the timing latencies as this is new and not optimized yet.

I have not built with 2-core yet, so please keep posting with what you find and how it turns out.

Just wanted to say thx for such a quick responce, and no I wont opt for the ddr2 600, if it can support 800 im going for 800

i am also curious how it will run with both parts at 1000fsb, 65ns and 800mhz ram

Yea that stupid intel page didnt work for me also, guess you cant link to it directly. but the info is here.

Opps, I did mean DDR2/800. typo on my part.

How old was that release??? 600, 600 & 1000 are relatively new.

i am also curious how it will run with both parts at 1000fsb, 65ns and 800mhz ram

Yeah, nothing ever matches up, but compare this with HD access of 4mSec and it really dosen't matter.

well with the CPU specs above it has 1066fsb and also runs at 65ns on this page for the mobo (P5WD2-E Premium)

http://usa.asus.com/products4.aspx?modelmenu=2&model=981&l1=3&l2=11&l3=

Front Side Bus 1066/ 800/ 533 MHz
Memory Dual channel memory architecture
4 x 240-pin DIMM. DDR2 800/667/533 ECC and non-ECC
memory Native DDR2 800 Support

So if both parts can run at 1066fsb and the CPUcan Support Intel next generation 65nm CPU - wont it run at 65ns?

The ram on the mobo can run ram at 800mhz, and the ram i plan on getting is also 800mhz?

CPUcan Support Intel next generation 65nm CPU - wont it run at 65ns?

65nm references the gap/distance between traces on the CPU chip. This does not reference nor equate to 65ns.

If one had to wait 65ns between ops & flops, we would be back closer to orig 8086 performance, 4.77MHz as I recall or 5 million cycles/sec

GHz is billion cycles/sec and this pup runs at 3.46 GHz, without looking it up. So that is 3.5 billion cycles/sec.
