OCZ 3700EB vs 4000EL vs 4400EL

[Gogeta]

I'm upgrading to a 3.0c, and am hung up on which RAM to get for the highest overclock while maintaining good timings.

First, there is the PC3700EB, which I hear likes volts, but runs (stock) at CL 3-3-2-8. OCZ's PC4000 Gold series run at CL 2.5-4-4-7, as does their newly announced PC4400 Gold. Not sure how these EL Gold sticks handle voltage though. I'll be cooling with a custom WC setup with an external rad/pump/hc enclosure (a la prometia cases, but with a PC-65 and an aluminum box). Blocks on cpu, gpu and nb. Mobo is p4c800 w/droop and vdimm.

I was thinking that if I get a good stepping, I will hopefully get to 270+ fsb at 1:1 3.3v. Just wondering which RAM will get me to those speeds with the best timings. Let me know what you think. Post personal results, or whatever
:D

afaik the 3700eb stock timings are 2.5-3-2-8 but most people can get them up to 240-250 fsb (maybe even higher) with 2.5-2-2-x and around 3.0 - 3.1 v More voltage doesn't seem to help them as they seem to get very hot. I used to have the Gold PC4000 ram which I got up to 275 1:1 with 3.1v and using 2.5-4-4-6 timings.


For 270+ 1:1 you will struggle with the 3700EB I would have thought but I stand to be corrected :)

You won't reach 4Ghz with plain watercooling, you'll be lucky to get 3.8 unless you have a GOLDEN chip. Get the EB sticks

Right on the money. If the 3700EB can do 3-2-2 at 240-250 with 3-3.1v, that looks damn good to me and should be perfect for your setup.

Am thinking of getting one of those sweet EB myself.

[naughty_guy]

it is very hard to get to 270FSB on a 3.0C on plain water. 3.0E might be more possible, if any.

[VoRtAn_MaDgE]

I get 263fsb on a 3.0 only with water, more than that he refuses to cooperate with me...cpu start loosing "strenght" before my mem's LOL

[Gogeta]

Hmm, you guys make a good point with the watercooling. Would a 2.4c or 2.8c overclock better? Trying to stay away from Prescotts :stick:

[mrflushysheaven]

ayeee......sicks......for.......

you can clock your mem higher on those. the CG oc's pretty good too. just a suggestion. are you into gaming?

[Gogeta]

Yeah, thats pretty much all I am :D

Right about now, a 2.8c with some 3700EB sounds awfully nice. I've only had my video card for a little over a year, and I just had it vmodded, so I wont be upgrading that for a while either.

I had a thought though. Since the 3700EB runs at 233MHz CL 3-2-2-8, will it be able to maintain these tight timings at ~260+MHz?

[saaya]

i dont think its that hard to reach 4ghz with a 3.0c , but im not into P4s, so im not sure. but iirc some people even reached 4ghz on air with 3.2c chips... search the forum.

for 240-250 go for 3700eb for anything above that better get 4000 or 4400.

[Gogeta]

Alright, well then I might just wait to see how high my new proc can scale before I buy the RAM. If I'm able to get to 260+, I'll get the 4000. It's $40 cheaper at Newegg anyways

[Geforce4ti4200]

get the eb ram by all means, its been proven that 5:4 at low latency will beat out 3-4-4-8 at 1:1 if your 3700eb cant take the high fsb, run 5:4 itll still own that pc4200 stuff at 1:1

[saaya]

ocz 4000 runs 2.5-4-4 though, and im sure it even does 2.5-3-3 with more volts up to around 270.

but i think your right g4ti, 240 2.5-2-2 in async will still be faster than 2.5-3-3 with 270

[brwmogazos]

sayya i think the 4000 wont do stable at ras to cas 3 at such a high fsb....i could be wrong though...as i havent tested it...

cl 2.5 or cl 3 doesnt really matter on intel canterwood and springdale boards though does it, ras to cas is more important :) ...so the EB would still be the better choise whethere youre running an amd or an intel rig :)

[saaya]

do you think async 240 2.5-2-2 is still faster than 270 2.5-3-3 1:1?

what if there was memory that runs 270 2-3-2 ? :D

[Rabbi_NZ]

i dont think the PC4000 or PC4400 likes the volts at all if it uses Hynix 5D chips, and I think it does... so 2.5-3-3 will only be achievable up to 240 if you'r lucky I THINK

[All Kill3r]

i dont think its that hard to reach 4ghz with a 3.0c , but im not into P4s, so im not sure.

gonna take a real lucky 3.0c to get 4ghz anything stable on air, atleast from my experience.. water i dunno, prob still going to be hard, its all up to luck but the majority of the 3.0c's won't make it. 270fsb on air is a lot with a 15multi.

go for the EB Gogeta :D

[Gogeta]

I think for the sake of not having to RMA something, I'm going to wait and see how far I can push my proc before deciding between EB or DDR500+ stuff.

That is, unless the EB at 217MHz asynch w/ tight timings will really beat a stick at 1:1 ~260MHz+ 3-8-3-3...

[saaya]

no, but it will clock higher than 217mhz, and at 240 it WILL beat the 260mhz 3-4-4 stuff. so yeah, start looking for the ocz eb already :)

i doubt you will see 260 3 8 3 3 mate...i had hynix d5 sticks...and up to 3.35v dimm...

i dont remeber running them thaaaaat high with ras to cas 3 etc...

Haha, ok :D

My DDR overclocking experience has sadly been limited to what the 845PE chipset can do, so I'm not very familiar with OC-friendly Canterwood/Springdale RAM timings. I'm very quick at doing the math for FSB/RAM speeds with a 4:5 divider in my head though :D
