Simple OCZ PC3500 EB Test

[wicktron]

I got myself some OCZ PC3500 EB because I was hearing all the great things about it and I was interested in hitting high RAM speeds without having to shove loads of voltage into the BH5.

This is just a simple test in SiSoft Sandra for unbuffered memory bandwidth.
Test setup as follows:

Athlon64 3200+ (10 x 220) :: 2.2GHz; 1.525v
Asus K8V Deluxe BIOS 01/15/2004
OCZ PC3500 Platinum Limited Edition (BH5) 2 x 256mb
OCZ PC3500 Platinum Enhanced Bandwidth (EB) 2 x 256mb

Timings are setup (CAS-tRCD-tRP-tRAS); Scores are setup (Int ALU/Float FPU)

BH5 (2-2-2-5): 2074/2076 | Screenshot
EB (2.5-2-2-5): 2065/2072 | Screenshot
EB (2.5-3-2-5): 2034/2055 | Screenshot

This test was done on my friends A64 system. Special thanks to chr6 for letting me use his system for testing. My system is currently down for case wire cleansing (gotta have that nice air flow).

Don't take too much away from this. If anything, you can see that OCZ EB is definitely good stuff (not like Wesley Fink didn't already conclude this). At higher DDR speeds, it should definitely pull away from BH5. The CPU used in the test does not allow me to overclock much higher, so I won't be able to illustrate the aformentioned point.

Cool. But, the only problem I see with that is the BH-5 will usually run 2-2-2-x at up to around 250fsb, even with only 2.8 or 2.9v. It'll usually do 2-2-2-x up to around 300fsb, with crazy voltmods. Points at shimmishimm

I didn't do unbuffered benchmark correctly. I have Enable SMT/Hyper-Threading Benchmarks disabled and have Enable Buffering/Block-Prefectch Benchmarks enabled.
I'll have to redo.

BH-5 does not usually do 250 at only 2.8v/2.9v. That's simply unheard of. Most with BH-5 go over 3.0v to reach such speeds.

Well, I don't have any, but that's not what the only two people that I know who have it say it will do with that voltage, Thugsrook and Shimmishimm.

Show me where they have BH-5 running at 250 at 2.8v/2.9v. Point me to it. If anything, Thugs runs a ratio, thus he is not running at DDR500.

Here, to illustrate my point:

Thugsrook running ratio

Shimm running near 3.3v

Most BH-5 modules need more than 3v to do >240 @ 2-2-2
In Wesley's review of the EB's, he has them running at DDR510 @ 2.85v, which is excellent compared to >3v for BH5 IMO.

When I get my system back up and running, I should be able to do a test with the EB @ ~250 if my sticks permit.

nice to see my name being thrown around...

3.25 --> 240 1 stick
3.35 --> 240 2 sticks
3.45 --> 250 1 stick
3.55 --> 260 1 stick

all with 2-2-2-5 timings bh-5's of course

I re-did the Sandra unbuffered test with the proper settings. However, there was <2% difference in numbers, so it's not significant enough to change what I currently have.

Haha, I spent 5 minutes trying to figure out how your name was spelled, Shim! I would have sworn that both you and Thugs had said that it would run ~250 with a more "normal" voltage. Obviously, my memory has failed me again. Well, sorry, Wicktron. In that case, being able to run at 250 with 2.5-3-3-x is great, because for some reason people keep buying the OCZ PC3700 that usually won't run less than 3-3-3-x at any speed (well, any speed over 200, anyway).

Note, I am not running 2.5-3-3-x, I am running 2.5-2-2-5. Wes has DDR510 at 3-2-3-6. I believe, and MS over at Lost Circuits has said this before, that tRCD and tRP are fare more important than CAS.
