SiSoftware Sandra Unbuffered Memory Settings

[Mikki]

Just thought it would be a good idea to post this, this is one of those things folks ask about all the time....;)

Here's an updated screenie of Sandra 2005 Lite SR3. Only slightly different, settings are the same.

Here is the P4C800 running Dual OCZ 3700 256MB chips @ DDR494 running @ 2-3-3-7 Unbuffered

[Radelon]

Hawk, I'd be posting some too if I wasn't having some weird issues...... Once it's figured out, I'm sure me and my P4 Mobile Wonder will impress some peeps.

Buffered:
Int Buff iSSE2 4700 MB/s
Float Buff iSSE2 4692 MB/s

Unbuffered:
Int ALU 2836 MB/s
Float FPU 2857 MB/s

Running Windows 2003 Enterprise Server with 50+ processes in the task manager. 2x512Meg of XMS3500C2 at SPD and no oc'ing of any type. Processor is 2.8C. Not so bleedin' edge but believe me, I'm bleedin' from the upgrade. :rolleyes:

I changed the memory to Crucial PC3200 ECC. And the new results with no oc'ing:
Buffered:
Int Buff iSSE2 4657 MB/s - down from Corsair
Float Buff iSSE2 4660 MB/s - down from Corsair

Unbuffered:
Int ALU 2793 MB/s - down from Corsair
Float FPU 2864 MB/s - up from Corsair

No surprises, it's ECC RAM so the results should be a little slower than the Corsair.

BTW: I did try tighter timings and the scores would drop by over 150+. So the best results were with 3-8-3-3 timings. :(

Thanks Mikki.I asked about how to run Sandra unbuffered benchmark yesterday.I totally missed this.:blush:

I guess since I am here I can post mine from my IC7 MAX3.

This is just a quicky I did a while ago maybe if I reinstall the ram in here and play with the timings I could do a bit better. This was just a speed detting.
The mem is in my p4c800 d right now and doesnt do as well there.
And the 4200 I have in here dont either.

[Killer Munkey]

i used the settings at the top and it cut my bandwidth score a lot.

with 2x256mb pc2700 at 2,3,2,7 CMD1 i got
Int ALU: 940
Float FPU: 996

with all the options check i get about 2300-2400 score on both. any reason why disabling the options is good or a better way to mesaure bandwidth?

[mysteryman]

Wow, do I have the record (at least in this thread!)! Ha!

Here are my scores:

Buffered: 6441 float / 6471 int
Unbuffered: 3481 float / 3329 int

[3246251196]

hello. i am new here but i was wondering. in a couple of days i am getting 2*512 OCZ 3700EB - is this good memory in your opinions? and what bandwidths do you think it will achieve?

Not anymore. Considering that I'm using 333fsb procs with 400fsb RAM that cannot be forced to run at 400fsb I think this is pretty good. :)

You need to read the first post in the thread. This is sandra unbuffered not buffered like your showing. If you want buff I can post a 6975MB/s 292Mhz 1:1 shot :thumb:

He has his unbuffered results one line below his buffered results. :)

How do you get unbuffered? Mine will no doubt not be as impressive as most.

I have a RAM timing question:

my settings on a p4c800e deluxe are 250 5:4 2-3-3-5-4

Is it better to have timings match up? Should it be 2-3-3-8-4 or 2-3-3-8-8?

That's two separate questions...

This is only my second post and I'm pretty new to overclocking...

Thanks!

Hooray! The attachment is back on the first post! It was missing the other day! Well done whoever!

If you have a motherboard that supports Intel Dual Channel Memory, read on:

Background

For background information on the Intel Dual Channel Memory Architecture, please see these documents:

Intel Dual Channel DDR Memory Architecture White Paper
http://www.kingston.com/newtech/MKF_520DDRWhitepaper.pdf

Dual Channel DDR400 memory can balance the performance of the Intel Pentium 4 processor with 800MHz front side bus.
http://www.intel.com/design/chipsets/dual_ddr_sb.pdf


Personal Experience

I bought a PC with a single factory-fitted 256MB DIMM.

I installed a matched pair of PC3200/DDR400 DIMMs - in the correct sockets - and measured the following memory performance improvement:

Pentium 4, 3.2GHz
Single DIMM 2947 MBytes / sec
Dual DIMMs 4664 MBytes / sec
( SiSoft SANDRA benchmark )

The Intel and Kingston documents suggest that this results in a 10-25% improvement in overall system performance.

Hope that this helps

I have read your stuff. It is an interesting and useful for me. I am appreciated for it. I am also glad that you have mention necessary configuration of it. You have nice way to explanation that any person can easily understand about it.

Thanks for the post.
Hi guys, Im a newbie. Nice to join this forum.

[RacingKen]

does anyone have the best (oc) timings for my (OCZ Reaper HPC Edition Dual Channel 4 GB : 2 x 2 GB Memory - DIMM 240-pin - 1066 MHz ( PC2-8500 )?
I have not oced them in so long I forgot or lost the timings I used before.:chit:

[RacingKen]

Ok I found them.:chit:
