don't worry, with me here you definitely wont be the last one at ddr2 i'm one of those 3-5 year change people

btw guys, need a bit of help. using extreem's screenshots i've managed to set up my 9150e at 2.5GHz, now i'm lowering the cpu voltage to find the lowest stable (complete opposite of usual exploration overclocking ) since i'm fine at FSB 280. my problem is my RAMs, they're rated for 1066, but i'm having trouble getting past post when i change the divider from 533 (3:4) to anything higher. even 667 (3:5) won't get past post, which i cant understand. pumped the ram voltage to 2.2 didn't help either. any ideas?

alrighty, i'll give it a shot and see how it goes. i've reset the cmos so many times that all the settings i could probably do with my eyes closed now my ram is hyperx, which i think should be the elpida chips since i only got the stuff around 2-3weeks ago.

NO WAY IN HELL! i refuse to use 400mhz divider

thanks for the tip ah_khoo, i set the divider to 800 and its doing well, had to lower my fsb a bit though, which sucks. lost about 70MHz, due to my ram's limitations i guess.

current overclock would be:
FSB = 272MHz
HT Multi = 7x (1400MHz)
NB Multi = 7x
CPU = 2448MHz
RAM = 1088 (5-5-5-18)

havent primed it yet, but i'll probably do so tonight after i test how low the voltages can go

for the proc i'm using?
the max i did was with fsb 280, which was 2520MHz. i believe extreem managed to get 2610MHz by using fsb 290.

yeah, for my board 284 was the highest i could go with all the other components at their lowest multiplier. Vcore was +200mv, so the final Vcore was 1.264 according to cpuz.

the main limiter with the 9150e is the locked multiplier. without headroom there you're limited by your max FSB, and the highest most can go doesnt need more than 1.3V

the board is a DFI JR 790gx mr2s, as stated in my siggie. NB was at 1.3 at the time. to reach 3GHz with that proc you need 333 fsb, nothing less =x the multiplier maxes out at 9x.

Btw fellas, i've been priming using 4 instances running custom with 400mb of ram to each. does this sound sufficient to test for stability? i couldnt run all the instances with blend because it tends to use almost all the available ram, so unless you run 1 blend and the other 3 cpu only i'm guessing what i'm doing makes sense?

could you post your settings? i'm not sure how the options are in prime 95, but when you use stress prime (which is a prime 95 front end) and you run more than one instance of blend, it does indeed cause one of them to fail due to lack of ram (they both fight for the whole thing, i think).

haha, i can definitely understand that. unfortunately, that OC was unstable in the memory test, i was getting errors in sp2004 and then i decided to clock it with memtest, also no luck regardless of the voltage. i didnt dare go beyond 2.25, and it was still erroring so now i'm pushing it back to the 3:4 (533) divider and pushing my fsb as far as it can go. i'll try it with p95 later sp2004 running stable for 12+ hours as i'm writing now.

current settings would be:
fsb: 285mhz
cpu: 2567mhz @ 1.26V
ram: 760mhz (4-4-4-12) @ 1.8V

will try tightening my timings again later i just realized that while its a lot of work, this is more fun than i imagined my old athlon was an unlocked chip, so there wasnt much to do, but when you're working with so many constraints its very satisfying to get the most out of your equipment!

i have to agree, for some reason the newer khx's dont live up to the name. right now i'm just benching this cpu cause its going to my sis to do her rendering work, while i move on to a "dual core". moderno, i'll be visiting you soon

as for the cas timings i was so pissed off at the damned rams for not working at 667 divider, and then some more the silly mobo go put such stupid timings like 5-6-6-18 on sub-800 timings. i was like nabei, take that! and then ran it through memtest now i'm satisfied a bit.

i think the only good thing about hte khx now is that its cheaper than other rams. for example, i was looking at some mushkin ram for ddr800 at 4-4-4-12, its around rm190. the khx kit was 145, and since my cooler is a S-N config rather than E-W, i can fill all 4 slots since the heat spreader is low profile

momuchi, you my friend are a scary guy

not sure about ddr3, but i was just checking some ddr2 rams from ocz, apparently the reaper's use micron's as well? getting some new hardware next week to sidegrade my pc and upgrade my sister's, so i think i'm already racuned into getting some higher performance ram considering that my kingston hypers couldnt go stable any higher than 1066 QQ

hohoho, i just collected my 550be from moderno! XD XD

sadly the rest of the pc will only be arriving next week, so kena tunggu sambil gatal QQ

hey there syazone, i see you're going to be OCing the CF batch its a good batch of procs we got then, almost guaranteed to be able to hit the 2.5GHz range if your mobo allows it.

check out the links at the first page of the thread, and maybe also this one, i found it very useful when i started OCing my phenom as well (i'm in the same boat as you, my last OC was also a barton )

other than that, once you're sure of your mobo's highest fsb, you can use the voltage settings from any of the 9150e users here as a reference, like myself and extreem. depending on your cooler as well of course

or all watching the footie game today

hey guys, need a bit of shopping advice though. i'm torn between the ta790gx-128m and the ta790gx3-a2. any recommendations on either one? i'm trying to keep my costs a bit low, especially since the mobo is now breaking my old budget (was planning to get an ECS, the 780 ultra since it has the sb750 on it) but having tested it on my friends PC, i'm really disappointed to have found that i could only hit a maximum FSB of 240. going to be putting my current X4 on it, so i definitely need something which can hit 280.

damn, now comes the question, to wait or not to wait getting a bit girang to put the whole thing together next week... haih, need to crack my head again

haha, thats just what i did. checking with some sellers now to see when can cepat dapat.

hmm, got a question. my ddr2 ram is also listed as ddr2-800 by cpuz. but its a 1066 kit. any reason why this might happen?

aha, thanks for the ram info guys.

and antonio, we're in the same boat bro mine is also sitting in its box, right now my room is like some pc shop, 3 extra chassis sitting around, some chassis boxes as well all thanks to the upgrading exercise we're running here

hoho, based on Regor. imagine if you could unlock it from x1 to x4 XD XD

But them Regor's are the ones we're unlocking to X4s aint it? But in all seriousness I doubt it too, knowing AMD they'll likely be doing something like laser cutting or whatnot to ensure it wont be unlockable, or these are chips that the other 3 cores are so screwed that even if you do unlock them there's no way in hell they'll be stable
