How to overclock my Memory to it's rated speeds on my AM2 system? (CORSAIR XMS2 2GB)


X-Kenshin-X

Recommended Posts

ok look, i got a CORSAIR XMS2 2GB TWIN2X2048-8500C5 set. i'll pair it along with an MSI K9N Platinum AM2 and an amd FX-62 processor, a Thermaltake toughpower W0103RU 600W, and it'll all be inside a Thermaltake Xaser III V2000A case (has 7 80mm fans). i don't think i need to mention the other stuff >_>, it'll have one hard drive 500gb, and 1 dvd-rw drive, and a dvd-combo drive.

 

now all i want to do, is overclock this memory to it's rated speed 1066MHz, or as close as i can get to it. the corsair tech support guys told me it'll automatically default at 800 when i put it in. so i don't wanna overclock my system to the third dimmension, i just wanna be able to achieve that speed.

 

i also read this article, http://www.tomshardware.com/2006/05/23/amd_reinvents_itself/ , which gave me a much better understanding of everything, and also saw this graphic, http://images.tomshardware.com/2006/05/23/amd_reinvents_itself/table_ddr2_memory_configuration_big.gif , which led me to understand, i might only be able to get as close as 1020, which is fine.

 

the problem is, i have NEVER changed any of the settings that deal with this in the bios. dun worry, i've looked at the bios before, i fix computers for a living, and i know how to work around it and change stuff, it's just i'm seeing there's several things you need to change for this to work (i think voltages, speed, maybe overclock the processor and crap, i dunno!) and as far as i see if you get anything even a little bit wrong, your system will be very unstable, which is the LAST thing i want! really, i put reliability over speed, i just want to make it run as it should.

 

so if anyone can help, it'll be much appreciated, thxs.

First of all we were not able to reach 1066MHZ with this motherboard. Please try to reach the highest frequency with the following settings:

 

Dram Frequency: 800MHZ

DDR Voltage: 2.2v

Cas Latency: 5

TRCD: 5

TRP: 5

TRAS: 15

Command Rate: 2T

CPU Multiplier: 10

HT Frequencyor multiplier: 3x/600MHZ

 

Please find the max stable CPU FSB and we'll work on it from there. Also survey your temps at max frequency.

well i won't get the last of my stuff until monday (newegg.com sucks), so it'll be until then when i can start messing with it.

 

but... i don't get it, all the settings you put there are default >_>. in fact i don't even think i have to move anything in order to make the memory go

 

Dram Frequency: 800MHZ

DDR Voltage: 2.2v

Cas Latency: 5

TRCD: 5

TRP: 5

TRAS: 15

Command Rate: 2T

 

except the voltage of course.

 

anyways, when i get it and build it on monday i'll check back here to see if i was able to find and change some of those settings.

ok, but uh, one more thing, what i don't seem to understand is, exactly what frequency will i get with

 

CPU Multiplier: 10

HT Frequencyor multiplier: 3x/600MHZ?

 

sorry but i just can't equate what cpu frequency those settings lead to :P . oh and don't i also have to change the cpu voltage? (i dun even know if you can, just tryin' to get all my concerns taken care of before i move anything)

all right, i finally finished building it (after 6 hours :zzzz:)!

 

aneways, in the bios, i can change just about everything, except the ram's voltage. anyways, i got 2 badass utilities with that came with this motherboard. i'll show you some screenshots, and tell me what to change from there.

 

here's the first one, it has 2 places i can change:

here's the status of the system (also my cpu avg temp is about 40-45C so i dun wanna overclock it much, just the ram, or whatever is necessary to get the ram to that speed).

aneways, as you can tell i can't change the ram voltage from there, but i can change it from here:

i'll also tell you, that it doesn't show it there, but if necessary i can change the HTT speed and multiplier from the Bios. it's set to HTT speed 200MHz and Multiplier 14x

Please try the following settings:

 

Dram Frequency: 800MHZ

DDR Voltage: 2.2v

Cas Latency: 5

TRCD: 5

TRP: 5

TRAS: 15

Command Rate: 2T

HTT frequency: 600MHZ/3x

CPU Multiplier: 11

CPU Frequency: 266

ok i tried it, didn't work, made system unstable, the motherboard reset the bios.

 

look, here's an exact display of the options i have avaliable in my Bios, they have limitations, so plz tell me what to change from here, OR the pics that i showed you in my previous posts (you did see them right?)

 

look, for the CPU, i have these options:

 

CPU Frequency: 200 - 425MHz

Processor Frenquency Multiplier: x5 1000MHz - x25 5000MHz

Processor Voltage: 1.1 - 1.45

Processor Voltage increment: goes up by .5 or .35 volts each

FSB Multiplier: 14x (can't change it)

MCP55(SB) to AM2(CPU) Frequency: 200MHz - 1000MHz (Default is 1000MHz)

 

 

Ram options:

 

Memclock Value: 400 - 800MHz

DDR Voltage: 1.85 - 2.45

Cas Latency: 2-5

TRCD: 2-5

TRRD: 2-5

TRAS: 15

TRRD: 2-5

TRC: 11T-26T

CMD-ADDR Timing Mode: 1T-2T

 

 

 

yeah i just did this a while ago, so i wanna get it today...

ok look, i finally got it, except, the settings you gave me didn't work...

 

neways, i finally got it stable, at a 11x mult, and 266 htt link. so now it's running at 2.916GHz, but the ram is stuck at 486MHz wtf?

 

oh and look, here's some pics of my bios.

this is what i got now,

plz help, i almost got it >_<

wow, thxs for the info, i guess i'll have to settle for something below 980! >_<, damn!

 

but might i inform you, i was able to reach a nice, 281 FSB x CPU Mult 11 = 3.1GHz cpu / 6 Ram divider = 515MHz(1030) RAM, with 4-4-4-12 timings :D: .

 

the only thing that sucks is... although it's stable in EVERYTHING else in windows, running programs and all, for some reason, the only place where it screws up is while running games. (i even ran a 10 min. sability test, and it passed it great). so yeah, if i could only figure out what the problem is with the games and 3d applications, everything would be fine. if i didn't game so much, i'd probably use that -_- .

 

i'll post a pic of the error i get later (and i know it's the overclock, cause once i downclock it to stock, the games run fine).
