Corsair @ DDR2 802MHz! 4-4-4-12

Post by Apoptosis » Mon Nov 08, 2004 3:21 pm

We have been playing around with some new Intel 925XE motherboards and have managed to hit 802MHz on the memory thanks to some dividers!

Update: Benchmarks

Test System:
Intel 560 w/ 1.7Volts on air
ASUS P5AD2-E-Premium w/ bios 1002.005
2x Corsair DDR2-SDRAM PC4300 - 512 MBytes w/ 2.1Volts on air

The performance levels are not nothing special, but the highlight here is the memory running 802MHz!

Everest Latency

Results: As you can tell the benchmarks still come in below some of the low latency DDR1 test systems even with our memory running 802MHz, our processor at 3.9GHz and our FSB at 1200MHz! I'll let you think about that for a bit and come to your own conclusions!

The first question is: "was it stable?"

But hell, ya... that is nice... hopefully the world of DDR2 will start shining!

I updated the post with some Everest benchmarks... Not the most impressive benchmarks, but saying my computer memory is running at 800MHz still sounds pretty neat.

Ya... I like the 802MHz... but the 4-4-4-12 isn't helping the performance any.

Hi Guys, Is this with an intel reference board or ??? I had similar results with an EE ES and a reference board intel sent me, it detected some corsar ram at 840mhz but the figures were very poor, around 5500 in sandra, much like the 5442 scores you got above. This seems very low even with 4-4-4 latencies, im putting it down to some quirk with the new bioses on the intel boards.

Testing the same ram in an ASUS P5AD2 at 700mhz figures were in the region of 6000 with the same latencies and with the new OCZ ram http://www.driverheaven.net/reviews/OCZ4200DDR2/ at just over 700mhz scores exceeded 7000 (granted with much tighter timings, but still).

This was done on an ASUS P5AD2-E-Premium w/ bios 1002.005

This board isn't really out yet and features the just released Intel 925XE chipset and we used our ES 3.46EE processor.

Even with all the new hardware everything has been detected properly. We are running a 300MHz FSB with the default multiplyer of 13. We then used a 3:4 divider to achieve the 802MHz frequency for the memory.

I'm pretty sure it's just a BIOS issue... Time will tell when more of the 925XE boards come out.

Also some of the older benchmark utilities gave inflated DDR2 numbers so make sure you are using the lastest versions! Plus in your post you compared my everest scores to your sandra scores, which is like comparing an apple to a lime.
