I have DDR2 800 ram sticks in right now (some cheap ocz stuff) Im wondering if I upgrade to 1066 would I have an easier time over clocking my E8400 higher?

If so, ive been looking into these two

Patriot Viper 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK

witch one would be better to get? If someone could give me an even better option than these that would be great.

linderman

any memory sticks by Corsair / Crucial / Patriot / OCZ / Gskill

are all decent ............ before you buy any ram make sure you use the ram manuf's memory selector to verify the sticks will work in your motherboard

next make sure you get sticks which are rated for Cas 5-5-5-15 not higher

make sure your ram is rated for voltages of 2.0 or 2.1 or 2.2 volts .......... avoid the sticks that can only be used at 1.8volts or 1.9 volts


dont expect to see yoru ram speeds at 1066mhz in the bios ....... it doesnt work like that very often .......... what 1066mhz is good at is having the ease to achieve overclocking which can sometimes be difficult with 800mhz ram ..........

once you get to 850 mhz and beyond DDR2-800 "can" start to get wobbley ....... 1066 will cruise easily by the needs of any cpu using DDR2 memory .......1066mhz just removes the possibility of "i think my memory might be holding my back my overclocking potential"

thanks linderman big help

so I ended up getting OCZ Reaper 2x2GB 1066 memory and I cant seem to get the timings right, it says on the ocz site they are supposed to be at 5-5-5-18 so I did that but im not sure how to set the voltage. In cpuz my FSB DRAM isnt set at 1:1

linderman

the ram ratio of 1:1 is achieved thru a setting ........ what is the make and model of the motherboard and we can help your with the ram dividers necessary to get the 1:1 you are looking for

10pmStalker

Ok I just got it set to 1:1 but now it says in cpu-z the DRAM Frequency is 400.0 Mhz. I now need to get it back up to the 1066. My mother board is Gigabyte GA-P35-DS3L

linderman

memory is double data rate ........ which means 400mhz memory is really at 800mhz


if you want more ............ try the 2.60 B setting

10pmStalker

what is the 2.60 B setting? I just want to run my memory at 1066 like its supposed to and at 1:1 if thats possable

linderman

it will not auto default to 1066mhz memory .............. you have to tweak it to get there ..........





enter the bios / in the SPD (sytem ram multiplier) there is a setting ......... choose 2.66B

10pmStalker

thanks for your time linderman. I tried overclocking my E8400 earlier, it didnt work and my motherboard reset itself. The ram is set at 1066 default. I took a picture of my bios and under the SPD there is manual and auto. Could you tell me what to do from looking at the picture?

10pmStalker

also heres a screen shot of my cpu-z

linderman

the setting I refer to can be seen as the same time on the screen as the CPU host frequency (scroll up from your last screen shot)

please take another screen shot and post it / a shot where you can see Cpu host frequency

linderman

you wont get a one 1:1 ratio with your ram set at 1066mhz

here is how it works ....................

say for example you have your cpu host frequency (cpu FSB) set at 400mhz and you choose 2.00 D memory multiplier ........ your ram will run at 400 x 2.0 = 800mhz ....... that will give you a 1:1 ratio

so for you ......... if you want to run a cpu FSB of 400 (the effective bus will acutally be 400 x 4 = 1600mhz) then you would want to run a memory divider of 2.66 C or D / this would give a memory speed of 400 x 2.6 = 1040 ........................... the B,C, D part of this relates to memory timings ............. the D setting gives the tightest timings ....... the B setting the loosest timings

you have to play with it to achieve what you are looking for


vdimm voltage should be at 2.0 volts (provided of course you ram is rated for such ???)

do you have a link for your ram ................ where you bought it ?

linderman

your motherboard is an excellent overclocker

linderman

your system drop down specs has an error listed ............... your cpu voltage is not 3.5 volts ............the fire department would have had to hose it down if it were at that !


i think you meant 1.35 volts (check the cpu-z tab for cpu ......... you should see it listed there)

10pmStalker

ok, I got my memory from here http://www.memoryexpress.com/Product...20232(ME).aspx Thanks for explaining all that. Helped a lot

10pmStalker

alright I got a few screenshots.





Please let me know if I should change anything or if that SPD @ 2.50 is to high. When it is at just 2 the memory sets to 800 800 so I figure maybe I will be able to over clock my cpu higher if my memory is set higher.. maybe im wrong. I plan to try to get stable at 4ghz

10pmStalker

btw what voltage did you set to get your E8400 to 3.8? I know it could be way different on mine, just wondering.

linderman

I got 3.8 ghz on stock voltages ............... had to go 1.35 in the bios to hit 4.0 ghz stable

linderman

you cant tell any diff between 3.8ghz and 4.0 ghz ............... so in my book 3.8 is a smarter move as its at stock volts


let me know what you want to do ...............


your screens look good
