I have an AMD 3700+ , 2.2 ghz 1 mb cache and 2000FSB
I havce tried ocing it with my cruddy ram and ctock fan, most i coudl go was 2.6, tried going to 2.8 and my hard drive went al lscrewy.
So i recently purchase Corsair Twin X DDR ram, 1 gb of it, the Thermaltake big typhoon and OCZ thermal paste.

but now i havea diffrent problem, i have no idea how to o/c ram, and how it works with the CPU, Can anyone hlep with my problem?

thanks.
 
if you want to oc the ram then you might have to bump the vlts up
a little.

when you oc the cpu it also oc,s the ram.

and if you really oc then you will want to loosen your ram
timming a little. something like 3.3.3.8. for a high oc.
 
i have o/ced the ram to 3.3.3.8. The CPu however is another story. I cant seem to get past 2.5 without a lockup. Why is this happening? Shouldnt better ram = More O.cing? Ivegotten further with the cruddy ram and stock fan, and this isnt making sense to me
 
Well i have a 600 W power supply, and Asus A8N5X Mobo.im pretty sure i have all the parts i need i just dont know whats wrong:S
 
I have recieved all the parts to replace the stock stuff.
The Thermal take big typhoon with fan controller, COrsair TwINX Dual Channel 2x512 and OCZ thermal Paste
 
ok what i have done.

oc a msi k8neo4 sli to 2.5, with a 3700,2 512 corsair xms
no vlt mods or anything.

oc (everything) the same but with an asus a8n 32sli deluxe
to 2.7, but 2.6 with 4 sticks of the same memory.

you should? be able to get 2.6.

go a little at a time. check temps and so on.
 
I have tried going slowly up and it still cannot go over 2.5
I think i know my problem.
The ddr ram i had b4 was only 333 Hz and i didn't bother o/cing it
This new ram is much fast and probably takes up more power. I think the reason why i get these lock ups is because the ram and CPU are hogging all the power and leaving none for my other components?
I'm thinknig this because whe ni clocked it to 2.7 i would get to the OS select screen THAN it would lock up. Hard drive had no power
WHen i tried at 2.8 i coudlnt even get to the OS screen. Mobo didint have enoguh power
Just my thoughts no idea if im right or wrong.
Should i turn the switch on the back of my power supply to 230W instead of 115W.
any input woudl be helpful
 
OK this ibothering me. I cant seem to find a way to get over 2.5!
I tried lowering the HTT multiplier to x3 and i woudl lock up. I tried to increase the timings of memory from 3s to 5 and 8 to 10. im still confused. Wht should i do to achieve atleast 2.8 or 3? Decrease multipliers? increase or increase ram speed? :S:S:S:S
 
whthe ram you have will be set at the same HTT (or FSB) as ur CPU.
so a 3338 timings at 400mhz is not bad but when u push that ram to 500mhz ur going to experiance dif.


look at it this way.

2.2ghz = 11 x 200 FSB
u ram is only good for 400mhz. when u raise the FSB u raise the ram speed.

ur ram may only be rated to run at 400 but as the reveiw here states the ram is only good for 456 FSB which would give you an overclock of 2.5

try putting in a ram divider (forcing the ram to run a set speed e.g. 200MHZ)


ur over streaching ur ram. not ur CPU.

my 3700+ runs at 2.8.

i run the ram at the native speed of 266. combined with my overcock gives me 2.8.


so lock the ram and the PCI/AGP multiper at 1ghz.
then underclock ur ram with the use of divieders to 266.


PM me if u need a giude. done this thousands of times with AMDs. will talk you right through the prossess.

what MB you using???
what PSU?
are u using a sandy core?
 
UGH! I tried bringing down my Ram like you said,brought it up to 2.775 GHz and put ram down to 200 Hz. I thought it worked until windows finally loaded, some errors screen came during the welcome screen, and while i was on the desktop the monitor kept flashing , blackingout and turning back on.
Restart my computer and im doing a hard drive test, after its done i can't getinto windows ... just reinstalled it. THis is now the third time this has happened due to overclocking problems.
What am i doing wrong!
 
You're goign to have to raise your vcore - the power going to the cpu itself. Also it'd be a good idea to set your ram to a low divider, something like 1/2. This will run your ram very slowly but at least you will be able to focus on just overclocking your processor, instead of worrying about your ram and cpu at the same time.

Now, when you raise your voltage, you want to do this very slowly. Too high and you'll fry your computer...

Which socket are you using, 939 or AM2? This is important to know so youi know how much voltage you can run through it. I had my 939 sandy 3700 at 2800 with 1.55V and it was rock solid... but I wouldn't recommend going higher than that for day to day use, and even this may be pushing it.

Anways, good luck. Just remember, go slow.

EDIT: I'm not sure what kind of motherboard you have but this should still work... on dfi-street.com there's a pretty nice OCing tutorial, that's what I used when I was first learning. I'd take a look at that.
 
First, what is a divider? lol sry, ram is completely new to me. My socket is 939, not sure wat sandy is, do u mean san diego core? and the voltage is 1.4. Ill put up the voltage after i learn a few more things, i dont want my hard drive to screw up again. I find it very weird, someone said i over headed the nb or sb, causing my hard drive to mess up. But the only files that are affect are the windows folder on my c drive, and data on my D drive gets all jumbled up(i open a song and its one of the other songs i have), or the files just go corrupt and i dont know wht to do. I got a program called handy recovery, work on soem of the files, know any programs for me to recovery all my lost data? i had alot ofsongs and movies and programs that are now corrupt.
 
Yeah, sandy = san diego core.

Unfortunately, I couldn't tell you how to recover your files, or exactly why they got corrupted... any number of things can go wrong while overclocking and cause problems like that, but I couldn't say for sure exactly what happened. If I had to guess though, I'd guess that it has to do with the RAM. I unfortunately don't have any experience trying to recover damaged files... so I can't really help you with this, and I don't even know how possible it is really.

My best advice to you, honestly, is maybe you shouldn't do this unless you are willing to take the risk of losing your hardware and data. Nothing personal or anything, just make sure you really want to to this.

If you do decide to continue, you really should bookmark/read through this:

http://www.dfi-street.com/forum/showthread.php?t=20823

That will explain everything you're going to want to do... far better than I could possibly explain. Again, some of this might be specific for DFI boards, but the general idea will be the same.

Now, as for the divider: basically this allows you to lower the speed of your ram. Your ram speed and cpu speed are based on your FSB.

CPU speed = FSB * CPU multiplier
RAM speed is approx. = FSB * divider * 2 (if your ram is DDR)

The ram divider can be anywhere from 1/2 to 1/1, I believe.

Normally your divider is set to 1/1 so your ram speed is:

200 FSB * 1 divider * 2 (DDR) = 400 mhz

So say you set your divider to 3/4 (this may be labeled as 150) and your FSB is set to 200. Your ram speed would be approximated by:

200 * 3/4 * 2 = 300 mhz<---- this is not exact (also explained in the link above)

Last thing: you're going to want a couple programs. I don't have the links handy but they should be in that link I posted above as well, or from google. The programs are:

motherboard monitor <-- allows you to monitor your temperatures
prime95 <-- stresses your system once you have a bootable overclock, run a torture test for at least 12 hours to make sure it's stable
memtest86 <-- makes sure that your ram isn't making errors that could corrupt data
occt <-- torture test, like prime95
a64memfreq <-- allows you to calculate ram dividers
 
I think i know my problem!
I tried your suggestions, turning up the CPU voltage, and lowering my ram frequency to 266. As for the divider, i have nothing in the ram setting in the bios for that:S i looked arround and some pple clock the ram i have to 3 4 4 10 1T, tiger direct says the ram is 2 3 3 6 T1, the defaults when i installed were 3 3 3 8 2T, so i changed form 400 MHz to 266, and 2 3 3 6 1T. Put the FSB to 250 from the stock 200 to get 2.75 GHz, and put the voltage to the max i could , 1.50. I was able to get into windows but it said i had a registry error, As the desktop loaded my monitor would black out and come back.
Next time i try to boot my windowsinstall was done.
I put my harddrive as a slave in my brothers compuiter. b4 windows booted it did a diskcheck on my C drive and fixed the errors. Right now im copy files i need to my bros HDD and im gonna do a format and fresh install jsut to be safe.
I did some checkingo n the maxtor site, and it said POwer FLunctuations can cause damage to my data. now i t all makes sense. The monitor was blacking out because my video card was getting bumpy power flow form the power supply ,same with the HDD. I have a 600W power supply but i dont think its very good anymore. I should of know for just 50 dolalrs CAN.
I'm not sure if im right, so anyone with some input plz share! Is it my power supply? If it is which one should i get to get my CPOU to 3 GHz??
 
I just recently OCed my 3700 to the max! It hit 3.01Ghz and I booted for a few mins and BAMMM I got the BSOD :evil: ! so I had to clock back a little. It was stable at 2.990 but I decided to play it safe and leave it at 2.900.
Its running like a champ.

Here is an Aquamark bench at stock(2.2) speed...
Oldscore.jpg

Im running a 7900GTO at 710core/800mem
I guess stock speed a lil bottleneck.
Here is a bench after the OCed

This CPU is amazing!

Too bad my JF bought me a OEM 4800toledo for xmas.
 
I have a 3700 and i am receiving bottlenecks with my 8800 GTX (ya i know i just had to have the video card instead of the processor hehe) Anyway, I was wondering if anyone knew how much i could oc this processor with the stock heatsink and fan. I may buy another heatsink and fan to oc more in the future but i was wondering if i could oc any right now and be safe.

Thanks,
Grunge
 
LOOOL wow... well i remember using stock when i had the CPU at 2.6 GHz, 90 degrees celcius when i ran 3D mark 05... might have been an error on the readings but it was probably over 60 C. With Big Typhoon I now am never over 45 C while playing 2142 with a 2.8 GHz O/c😀.
The only thing about o/cing that bothers me is lowering the ram speed, for me to stay at 2.8 i had to bring the ram down to 166 from 200, i could tighten the timing more but i noticed my xp loaded alot faster when i put it back to the stock 200. however with a game like 2142, with alot happening, the 2.8 Ghz o/c handled alot better than the stock 2.2
 
Does anyone have an answer besides "LOOL!"?

I mean i know i cannot oc much if not at all considering the stock heatsink and fan. But i would like to know what i could safely oc too without another heatsink and fan.

Thanks
