Which RAM is better for overclocking?

[carmaster22]

I just got an Opty 165, DFI Lanparty UT nF3 Ultra-D, and I need some good RAM to overclock with. Which one do you think is better?

OCZ EB DDR PC-4000 2x1024MB Platinum Edition Dual Channel Kit
Part Number: OCZ5002048EBPE-K

or

OCZ EL DDR PC-4000 2x1024MB Dual Channel Platinum XTC
Part Number: OCZP5002GXTC-K

XTC is the one with honeycomb heatspreaders right? I don't think it makes a difference. I would pick whichever is cheapest.

Those actually have different memory chips. The XTC can generally go higher, close to 290, but you'll need a lot of voltage to get it up there (around 3.6V) and the timings are slightly worse than the EB. I think on lower voltages the EB may go a bit higher, not really sure.

You can't really go wrong with either one though. I have the XTC sticks since I got them really cheap on ebay a while ago.

these are the ones i've been wanting

OCZ EL Platinum Revision 2

i looked for a link and found one for the non-XTC that you listed.

OCZ EB DDR PC-4000 2x1024MB Platinum Edition Dual Channel Kit

i think these were less than $200 for the pair.

 

[carmaster22]

Thanks for your input so far. Depending on where you go, both are about the same price (give or take $10), so that's not a big concern for me. I just want to get the best for overclocking.

Anyone else have any thoughts?

 

[imhungry]

I'd go with the XTC.

But the Platinum has lower stock timings, could show something...
XTC only because I like the heatspreaders better.

Maybe this is a better question:

I have an Opteron 165 (CCBBE 0610) and a DFI Lanparty UT nF3 Ultra-D and I would really like to hit 3GHz (on air with a Zalman CNPS9500). I'm looking to buy 2GB of RAM, what do you guys suggest?

 

[ryderOCZ]

Well considering you need 333 HTT speed to get 3GHz on a 165, there is no ram that will run 333 in a 2GB kit, so you are going to be on some kind of divider.

I would choose the OCZP4002GK, OCZ5002048EBPE-K or the OCZ5002048ELGEGXT-K.

As long as the OCZ DDR500 EB ram is still made of the Infineon ram, then get that. You can hit extreamly high OC's with it at really low voltages. (like all the way to 290mhz on just 2.6v @ 3-3-2-7, or even faster timings). Now that might be a lucky OC, but it's within reach.

Not sure if they still use those same Infineon ram though, didn't they switch to TCCC or TCCD? Not really sure.

 

[CP5670]

I think the Infineon CE-6 sticks have that strange 3D issue though, right? (where it runs prime and memtest all day at high overclocks but crashes in 3dmark and games) Although it will still probably clock better than the micron-based XTC unless you use high voltage.

I have an Opteron 165 (CCBBE 0610) and a DFI Lanparty UT nF3 Ultra-D and I would really like to hit 3GHz (on air with a Zalman CNPS9500). I'm looking to buy 2GB of RAM, what do you guys suggest?

3ghz is a bit of a stretch on that one, they usually seem to fall just short of that. Mine actually does "only" 2.85, although almost all the others I've seen go at least up to 2.9.

The xtc will overclock the least and has slowest timings.

Theres a reason the platinum EB has been upwards of $250 for a while. It has low low timings and is even able to do 2-3-2-7 or so at lower than 250mhz. The XTC would never get that low. The xtc had trouble even going lower than 4-3-3-7. The platinum EB can do like 2-3-2-7 if its under 250mhz. ALso, most newer XTC ive seen cant even overclock past 10-20mhz. The platinum EB is known for getting around 280-290mhz so.. Of course ymmv on all that.

Honestly if you dont plan on ocing and dont care about a little performance hit in timings, id just get the cheapest stuff.

Yup, I have the Plat. EB stuff and they are great for OCing. They OC like mad, but right now I only have them at 250mhz (3-3-2-7). I'm almost postive I can get faster timings and more mhz out of them. Just that I need my computer to work now so I'm leaving it were they are. It's always YMMV, but you have pretty good odds with the Plat. EB.

So, do they still use the Infineon (sp?) ram (CH-5/6)?

That would have to be a really good pair....I wouldn't say they are known to go that high. There are some out there that have....but its less than 1% I would say.

255 - 260 is about the average for pretty much all of our DDR500 Rated 2GB kits.

Yeah, my point was the Platinum EB is going to probably OC with the most potential than that XTC stuff. Anyways, I did see a few reviews on it and they achieved 280mhz so...that is why I said that. Youre probably right though. Either way, the platinum EB has killer low timings for being 250mhz.

 

[carmaster22]

Very good info, thanks.

Looks like I'll be going with the Platinum EB.

 

[keldog7]

I agree completely with ryderOCZ...you'll never hit 333 with a 1:1 timing ratio, meaning you'll be using a divider. The real question now is:
...just how fast do you want your ram to run. And given that RAM faster than 250MHz will probably have negligible real-world effects, I suppose the REAL real question is:...how much do you want to spend?
