Kingston HyperX PC4000 to OC AMD 2500+?

[Drizzy]

I see that this memory has pretty lame timings (3-4-4-8-1T) but my question is - would this RAM, since it is 4000, allow me to OC my system as far as the cpu and mobo would allow? I am assuming that since it is already at a much higher Mhz that it would in no way be a limiting factor in OC'ing... is that correct?

Also, would I be able to set the timings lower than the lousy 3-4-4-8-1T default if I ran it at a lower Mhz - such as 3400? Would it be possible to get it down to like 2-3-3-6 or something? I know when you push RAM above its default settings the timings usually get loose and I am wondering if the opposite is true - lower than default Mhz you can get tighter timings...?

I think you'd be better of with something like OCZ 3700 Gold... assuming there's no incompatabilities between that RAM and nForce2 boards that I don't know about.

 

[Drizzy]

I'm mainly just considering this RAM cause its on a great sale right now for 512 MB for $99.... the price makes me want to buy 1GB of it.. and I want to see if it will work the way I would like... thanks for the suggestion though.. I actually will be buying OCZ if this RAM isnt what I hope it is..

This OCZ low-latency PC3200 for $105 per 512mb stick would be MUCH better for both an nForce2 system, and a P4-based system: link to OCZ low-latency at newegg.

 

[Drizzy]

Its an AMD system that I'm wanting to OC to around 220 with the lowest timings I can.. I havent been able to find a good review of the OCZ 3200 Low Latency anywhere! I am curious what the timings will be at about 225 Mhz... Anyone help me out or have this memory??

 

[Dman877]

PC3200 - 3700 is what I would recommend for ocing that chip. Good brand of 3200 can do 220 - 240mhz fsb with decent timings and thats a helluva an oc on a 2500.

Screw O/C'ing. Buy some HyperX DDR333 RAM and set the CAS latency to 2-2-2-5-1T. I'm running a Barton2500+ with the HyperX DDR333 RAM and 2-2-2-5-1T timings makes my system fly!

 

[Drizzy]

Ok well, I'm trying to figure out which type of RAM I should get - they both are about the same price right now...

1. Kingston HyperX PC4000 DDR500 RAM. Default settings are 3-4-4-8 but I read that is cause its an OC'ed 3200 chipset and so it should run around 2-2-2-5 up to about 215 Mhz. 2.5-3-3-7 up to 230 Mhz.

2. OCZ Low Latency PC3200 DDR 400 RAM. Default settings are 2-3-2-6 but I want to OC this from 200 Mhz to 225+/- Mhz. I'm curious if this RAM will have good timings around 225 Mhz.... that is my problem. If I could find how well this RAM OCs then I would simply go with whichever one would have better timings around 225 Mhz.

PLEASE HELP ANYONE!

How high of an fsb can your processor handle? Alot of people recently have been having problems even getting their XP2500's to hit 200fsb. Oh, and there is someone on this forum who says his OCZ will run 2-3-2-11 (the fastest speed for an Athlon nForce2 board, besides 2-2-2-11) at 220fsb at 2.7 or 2.8v, if I remember correctly.

 

[Drizzy]

Did he say what model of OCZ he had? there are no guarantees my processor will go as high as I want but I'm going to try this on a few different systems.. one for me and a few that I am building for other people and so I hope that on atleast 1 I can get up to 220-225... that one will be mine of course.

Actually... the PC4000 might be better in a socket 754 system since you won't be able to run dual channel to get a ton of memory bandwidth. From what I remember in the benchmarks, the latency doesn't make a huge difference for some reason now with the memory controller on die on the Athlon-64. Who wants to be the guinea pig?

Haha, an XP2500 isn't an Athlon64, Jeff. But, at $83 for a 512mb stick, I'd be very interested to see what timings that HyperX PC4000 could run at 210 or 220, myself.

I don't recall saying it was...

*EDIT* BTW... I believe a lot of those high speed ones say that just because it might be rated for 2.5-3-3-6 @ 233 Mhz, doesn't mean it will run 2-3-3-6 @ 200 Mhz. So I wouldn't count on buying "fast" RAM, underclocking it, and getting better timings.

Also with a Athlon timings aren't nearly as important as FSB maybe 1 or 2 % while normally when you lossen up to timeings you get another 10-20mhz out of the chips which is much more benificial, espesially if you have an unlocked chip like the mobiles, or older standards

I am running 512MB of Kingston HyperX PC4000 and I can only squeeze 220FSB out of my 2500+. I really do not want to go any higher than 1.8v. Right now it is 220x10.5 - a nice little o/c in my opinion...look at my rig for more detailed information...

 

[MDE]

I got my HyperX PC4000 to run at 11-3-3-2 timings (@400MHz FSB) on my NF7-S.

 

[11427]

And FWIW I run my HyperX PC3500 at 2,3,3,6 with a 2500+ at 400MHz fsb on an A7N8X Deluxe

 

[lavaman]

I would go with a couple good sticks of PC3500 since you will still be able to run at aggressive timings (usually 2-3-3-6) and you can pretty much gaurantee the memory won't be the limiting factor for your OC.
