Cant get DDR3 to run at 1333 or 1600

[Timlander]

Well I cant get my ram to run at anything higher than 1066. Iv got 8GB so i know it will be hard to get it to 1600. But I woulda thought at least 1333. But everytime i set the timings and clock in bios it wouldnt post. Tried it 3 times till i just said screw it. Can anyone help? I heard that DDR3 overclocking was different, is it?

voltage buddy - i made darn sure to send at least 2 volts to the memory but im on 775 still. i dont know if i7 can handle that

your sig dont have any of your comp specs and i dont know them off the top of my head

[Hondacity]

set it first to 6-6-6-20, that way its free breathing, the tighter the settings that harder.

as marne said, vdimm is also necessary. if its i7 you can do 1.8v, if its c2d or c2q, some rams can go as high as 2.3 volts without damage...try 2.1v at first...

whats the motherboard anyhows?

[Kayin]

Those are only supported through OCing on AM3 at the moment.

hey Marne, i love the avatar, thats the tri-blade guy, from what anime is that again?

[Timlander]

Well...damn...I looked for ram voltage in there before and couldnt find it. What is the name it goes by again? Vdimm? cause there are like 6 or more ones to choose from. I guess I can take some pics of the bios screen for you if you want. And btw, i cant fit my comp specs in my sig, sry it wont let me, here are my comp specs:

CPU: Phenom II 955
Motherboard: GA-MA790FXT-UD5P
Memory: 8GB OCZ 1600 7-7-7-24
Graphics Card: Dual Fire HD4850's
Hard Drive: 250GB WD
Power Supply: OCZ 750Watt
OS: Vista x64

[Timlander]

Ok so what do you suggest i set the settings at? The ram states voltage is supposed to be at 1.9 @ 1600. What settings do you think I should do to try and get 1600 or 1333. I tried 7-7-7-24 as well as 6-6-7-24, but that was without messing with voltage cause i couldn't figure out which one was for the ram.

[Timlander]

Also to answer this, that is from bleach. Love that anime series.

[Hondacity]

oops i just saw your ram specs, set it to around 9 9 9 24,

ddr3 voltage control in the bios


read this stuff

http://www.tomshardware.com/reviews/790fx-socket-am3,2277-11.html

they got the ram to around 1500s but at 9 9 9 28

[Timlander]

A 9 latency!!! WTF IS THIS??? Why? =( And i do not remember seeing a DDR3 voltage control in my bios. It is the latest version, ill go in there now and check it out again.

[Marne]

avatar - That my friend is Ikkaku Madarame from the anime Bleach using his Bankai -- they have the entire series on Veoh.com. just search for

Bleach Tmrider

once his stuff loads set it to go to most recent and start at the last page. episodes 1-219 i think are on there now. i absolutly LOVE this series and im a die hard anime fan ^_^


timlander it should say vdimm or sumthin like that. i suggest putting it to the stock settings 1st (timings and voltage) than work your way up from there SLOWLY - just like a CPU OC you can burn memory quickly

[Timlander]

OMFG I see it now(the DDR3 Volt control). Damnit I feel like an idiot now...ok now that i find it, which settings do you think I should do for voltage, latencies and clocks? Whatever would give me the best(fastest) ram results. Also should I increase the NB voltage by .1 as iv seen a lot of people do?

[Hondacity]

is that the platinum ocz 1600 77724?

if it is so set the ddr3 voltage control to around 2v (rated voltage is 1.90-1.95v) it should be able to take 2v.

set timings to around 9 9 9 28 (just like in tomshardware)

dunno what fsb to use, i'm amd noob :D

ram:fsb in intel is very related...so for amd i'm not sure



thanks for bleach info(marny tim) i love that anime, its been awhile since i watched tv, i'm in OC rehab hahahah

That sucks a big latency is gonna slow it down. But there is a ram clock cfg where i can set the clocks anywhere from 5.33(1066) up to 8.00(1600).

[Hondacity]

those are the memory multipliers, what is your fsb at the moment? whats your cpu speed now?

latency of 9 isn't that too bad if you run high ram speeds...

but if you run low ram speeds you can tighten the latency/timings of the ram

Which should I do, tighter timmings @ 1066 or higher speeds at 9 letency? My cpu speed is stock, fsb 200, cpu multi X16, clock 3.2GHz. Also what voltage? you said 2 or 1.9 will work?

[Hondacity]

if you can set it up to 1600, id stick with that even with 9 9 9 28, oc your cpu already 3.2ghz is way t0o low :D

[Timlander]

here we go!

[Hondacity]

awesome stuff dude, download everest there is a ram test there and it shows the final ram speeds :)

[Timlander]

just google everest? iv never used it before. HERE (http://www.lavalys.com/) is the link I found. It also said for win32 platforms. Im running vista x64 do they have a version for it?

[Hondacity]

hmmm download all if it works then it works :D

i know i've tried it on my vista, but anyways it will show more info on the rams than cpu-z

:)

[Timlander]

Alright im doing a defrag on my comp now, ill get it in a little bit once that is done.

Still defragging 2 hours after I started it...GEEZ!!!

[Timlander]

UPDATE: Well i got memtest and did the test on my ram, and it found errors...voltage was at 2, 9-9-9-28 timings and 1600. So i changed to 1333 and left everything else the same, another error this time my computer blue screened. Now iv got the ram at 1.9V, 9-9-9-28 timings and 1066 in the bios, i overclocked the cpu on the FSB by 25, making it right under 3.6 and the ram right under 1200. Doing prime95 now and will do memtest in a bit as well. Bah aggravation. I cant RMA 2 of the ram sticks for cash back now...its too late...but if i sell them i will only be able ot get like 45 or so for them probably. Iv heard its a lot easier with only 4GB, I was just optimistic that it would work with 8...I guess not...Does anybody suggest I do anything different? Would AMD overdrive work better possibly?

[Timlander]

Seems like this overclock is pretty stable so far. Just got done gaming for 2 hours on it after the prime test.

[Hondacity]

push the voltage to 2.05 or 2.1v

[Timlander]

push the voltage to 2.05 or 2.1v

you sure that wont fry the chips? Im no expert in ram overclocking, and i have no way of telling if the ram is getting too hot or not...i do not want to burn $200 in ram...they are stock 1.9V.

[Hondacity]

it won't fry it, but i won't gurantee it, some ram vrm are noisy killing some ram, i've been overvolting my rams since ddr2 days, ddr3 is very fortunate for me i've been overvolting my 1.65v rated ddr3 at 1.8v, so far they're still alive,

if they're rated at 1.95v you can usually add like .15v max, more than that its too risky.

[Timlander]

They are actually rated for 1.9 and I would say 2 is the highest I want to take them(which is where I have them now). But for now, i am overclocking them a different way. If I remember correctly, there were no settings before to chance the ram multiplier(DDR2) or none that I have ever seen. So as iv said before on here, im overclocking it this time with the cpu on the fsb and am gonna see how far I can get this way. Maybe it will work better like this. A 25MHz fsb overclock has yielded me a 2.6GHz cpu clock and 1200 Ram clock. I know what iv got it at now it stable(stock Vcore too), i did 2 hours of prime95 and then gamed for another 3-4 after that with no issues. So I am really hoping that this way will bring me a bit more luck.

[Kayin]

If that's a 955, you honestly get a LOT more mileage out of multi than FSB. It breaks a lot of rules.

Well ill be doing the multi too. I just wanna see if this helps with my ram overclock. Cause so far nothing else is... Oh btw, what is the max safe Vcore I should use with the 955? 1.5? Also, how much better would using just the multi be? And can it still do well by overclocking the fsb a little then upping the multi? I just dont want my ram sitting at 1066!!!
