SB could you "PLEASE" POST a siperPI 2m with that EB mem at 253 ? "PLEASE"

Sierra_abx · 06-21-2004, 03:58 PM

I have to go to work soon, so I don't have time to bench and grab a screenshot. I think I get around 1 min 15 secs for SuperPI 2M @ 252-253 with the CPU at around 2.67GHz. I was hoping for better. Actually I can run at 252-253 without a divider. I was at 253X10.5 running 1:1 last night. Rock stable. But my goal is to run above 2.7GHz, 3D stable, 24/7. I think I'll be able to do that. Once I find a way to get more VDimm, that SuperPI time will drop. OPP has 3500EB running at 3.4v I think. His sticks can do 270-280.

By the way, my X800XT just arrived. But it figures that it came right as have to go to work.

I am stuck having to hold out until comp gets something in the store video card wise. I just can't see paying $500 when I can pay $40 plus trade-in. So I wait and wait . .

I did a bunch of reading this afternoon, and SB I think you allready did...because looks like your right as rain about the OCZ-EB working well all across the A64 platform.

I think I'll get some of this OCZ EB stuff. Only OCZ EB I could find localy was at Fry's and it's anly PC3200..

Think the 3700 is that much better ?

Sierra_abx · 06-21-2004, 05:47 PM

You'll probably get a higher overclock with 3700EB, maybe 10MHz higher on the RAM. The one thing to be aware of is that the EB sticks get hot. A fan pointed at the RAM is almost a must. If the sticks get too hot, you will start seeing heat-related errors during benching. Excaliberpc has both the 256 and 512 modules.

Sierra_abx · 06-22-2004, 12:04 AM

Hee hee. Charlie just finished a DI session.

xgman · 06-23-2004, 10:33 AM

SB, so what's the final verdict on the 3700EB's. Do you have 2x512 now? Are they the best for the 939 boards?

Sierra_abx · 06-23-2004, 01:09 PM

I should be getting the 512's today. I like the fact that I can run EB at 252-253 all the time with no problems. But I'm still working on trying to run above 2.7GHz stable 24/7. Need more VDimm. I think the 3700EB is a little better than BH-5. Running Cas3 seems to work well. Cas2.5 doesn't make much of a difference. The only major negative is that the EB sticks run hotter than BH-5.

xgman · 06-23-2004, 02:21 PM

I have some coming too. Ryan says that they take voltage very well. Normal 250's 3-2-2-5 timings should be better than 2-3-3 or 2.5-3-2. they do need a fan over them.

Sierra_abx · 06-23-2004, 02:27 PM

I haven't tried 3-2-2-5 yet. 3-2-2-10 seems to work well. As I mentioned earlier, switching to 2.5-2-2-10 doesn't seem to make much of a difference.

White94Cobra · 06-26-2004, 03:59 PM

Hi all... I just put together an FX53 system with an Asus A8V. I'm coming from an Intel world so I'm experiencing difficulty overclocking. I have the latest BIOS installed from Asus's website, but I don't think the AGP/PCI lock is functioning. I have OCZ PC4000 dual channel gold but I can't get the system to boot past 220 MHz FSB/HTT (no matter what multiplier I use). What settings should I be adjusting when attempting an overclock? With Intel I just changed the FSB and kept the memory at 1:1. I could get to 255 MHz FSB with my old P4 2.8, but not so with AMD. Thanks for any help!

BTW - where can I find bigtoe's BIOS for this board?

Sierra_abx · 06-26-2004, 04:12 PM

Bigtoe's beta BIOS (1005.021) can be found at bleedinedge.com. You have to register to gain access to the BIOS. 1005.021 will give you the AGP/PCI lock option. A64's overclock differently than the P4's. You don't necessarily need a high FSB, especially with the FX, because you have a full range of multipliers. Many benchmarking records set with FX processors, were achieved with a FSB (it's called HTT for A64's) of 240 or lower. If you want to run 1:1, make sure Memclock is set to Limit and then choose the option 2:1 DDR400.

White94Cobra · 06-26-2004, 05:29 PM

Thanks for the reply... out of curiosity, what would be the best settings to get ~2650 cpu speed, and 500 MHz DDR speed? Also, as long as the CPU is running cooler than 50c, is 1.8v too much? I cringe at that voltage, but it seems many run that high (vs. Intel where anything over 1.7 is considered suicide). Thanks.

Sierra_abx · 06-26-2004, 05:40 PM

I am using OCZ 3700EB which can go up to 250-253MHz (DDR500) @ 1:1 with only 2.8v. And that's with timings of 3-2-2-10. I've also tried BH-5 sticks which are great for tight timings, but there's no way they can hit 250 @ 1:1 using stock voltage. I have heard Corsair PC3200LL (CH-5) also works well in 939 systems, especially with VDimm mods.

I would not recommend VCore of 1.8v with air cooling. I run at 1.8, but I have a water block.

White94Cobra · 06-26-2004, 05:45 PM

Hmmm... my Intel box was watercooled, but it developed a leak so I thought I'd try air again. I'm using that new Tower112 from Thermaltake. Right now at 1.775 and 2.5 GHz I'm running 38c (I can get it down to 34c if I turn the fans on full). Full load seems to be around 46c measured with the latest Asus Probe.
