New OCZ Platinim PC 4800 EL not overclocking well with Intel PLZ Help!

hackerneeds · 07-15-2005, 12:56 PM

Once again my inexperience is shining through when it comes to overclocking OCZ memory on an Intel platform.

Here is the situation:
As I show in my signature I have a P4 3.2C CPU on a P4P800 mobo. I am running 1.6v vcore and 231 FSB (vcore 1.6) stable on all prime95, 3dmark tests. There are no errors overnight on Prime and the 3dmark runs without a hitch. (This is, however, with my ram ran at 1:1 (400) or 462 with my overclock)
I have the mem voltage at 2.85v and the AGP locked at 33/66. All settings otherwise are at auto – no turbo and no performance modes enabled. (So basically all default except for CPU and memory and AGP locked)
I tried to run a simple 4:5 (500) speed for the OCZ Platinum PC4800 (600) EL memory giving it 577.5 with my overclocked FSB but I had no luck; even at the loosest timings my board would go 3-4-4-8.
So then I started to back off the FSB on the CPU and leaving the memory multiplier running at 4:5 (500). I tried CPU FSB's of 225, 220, 210, 205, and 201 with no luck - I couldn’t even boot. (I did not try 200 knowing that PAT would kick in)
The memory runs well at a multiplier of 1:1 (400) making it 462 with my CPU FSB at 231, but can't hack its loosest timings at 4:5 (500). The true speed rating for these chips is 600. I am disappointed in the Intel performance.
I don't know if it is the memory controller on the Asus board or it the CPU just doesn't like them. Boy am I bummed though.
I have quite possibly the best pair of memory on the market, yet my overclocks are rather weak.

I have heard form many reviews that these same memory chips perform over FSB of 300 in all of the tests on an AMD 64. It is strange that they are so much worse on the Intel platform. (Maybe a warning should be posted instead of saying, "optimized for AMD 64 platform)

Is it true that you do not need to or benefit from some kind of burn-in on these memory sticks?

As you can see I just bought an AMD 64 so maybe I will have to use them in that computer and, dare I say it, buy another brand like Corsair's top of the line. I would prefer not to, especially since OCZ tech support has been so good to me.

Any suggestions would be much appreciated.

Last night I got the system to run at mem settings of 500 while at 200FSB no PAT. However the computer would not pass prime 95, it actually failed at around 2 min. I could get through 3dmark, but I am not interested in an unstable (error producing) overclock. My scores with 1 stick of Corsair xms 512 @ 5:4 (333) running 2-2-2-5 were 9300 on 3DMARK'03 while FSB was at 231 "stable". Now while at FSB 200 (No PAT) with the ocz platz 4800's at 4:5 (500) 2.5-3-3-8 my score was 8999.

I bumped the memory up to 3:4 (533) and loosened the timings all the way to 3-4-4-8 and the machine remained unstable and would not complete 3DMark '03. My volts have remained at 2.85 the whole time. I have a DDR booster, but read that increased volts really doesn't help these platinum’s very much (if any).

One last thing, I pulled the battery out of the mobo and removed the jumper that is 1/4 in away from the battery for 30 sec while unplugged and even switched the jumper from 1-2 setting to 2-3 setting for 20 sec. After returning the jumper to original settings and replacing the battery I loaded the system and it said load default settings 1, enter setup 2. I chose defaults and when I checked the bios version it was still the latest bios. I am assuming that this means that I didn't correctly reset the bios?

-Any suggestions would be appreciated on all subjects.
Thanks

Hey hackerneeds,

This memory is really meant for AMD 64 systems, but I do think it should be able to do over 200FSB easily on your system. I would suggest that you first try testing out each stick on it's own to make sure that one of the sticks isn't simply bad. Give that a shot and let me know what speed you can reach with each stick. Also if you haven't done so already flash to the latest bios.

One question, Why are you wanting to run the ram faster than the cpu? From my experience running the ram faster than the cpu nets you very little to no gain in performance.

hackerneeds · 07-15-2005, 06:00 PM

I was under the impression that running the memory at 4:5 (500) with the FSB at 231 would give me mych better performance than running 1:1 (400) with the FSB at 231.

btw - I have flashed to the latest bios v 1007.003 for my mobo.

I know, I thought the same thing. I saw marginal bandwidth increases. I may be wrong, but the way I think about it is that with a 4:5 divider, that for every 4 cycles the front side bus makes, the ram does 5 cycles. So there is a gap in where the ram is ready but the front side bus has not sent any information yet.
