abit of help with overclocking

conzy

Np;) , anyone thats overcloking should make sure that they have a PCI bus lock, if not the speed of the PCI bus will increase with the FSB and all things linked to the PCI Bus such as SATA, AGP, Will increase and cause instability, damage, data corruption...................

Claregalway, Any word from ASUS? Why not try and flash it? You will eventually have to flash it anyway!

The only potential problem that I see is That, Siemans just removed all the ASUS eeproms and replaced them with their own smaller pre-flashed eeproms.

Ao the official ASUS bios may not fit on a Siemans Eeprom, if you know what i mean.

Any news? Dead motherboard? fried Processers?:D

Drapper

no word from him but I need help keeping my rig at 2.8 any tips?

can get it but not too stable ! not sure how to loosen ram

Multi 12

any tips?

conzy

So you are running 12X 233mhz now???

You can loosen timings in the bios, under Dram configuration.

Did you find the max speed of the CPU and ram individually first??

If you didnt, there is no point in going any further until you do, as you wont know which component is holding you back;)

Gotta Go Im missing LOST:eek:

Hope lost was good

my FSB is 225 * 12 = 2700
my RAm is running at 225 (1t) 2.5 - 3 - 2 - 5
STABLE

sorry I know where to change it in the bios ! doh....... but if I overclcok to :-

233 * 12 = 2800 (fine win start up)
Ram = not sure

I get resets! :-(

any tips !

conzy

Ok, Have a look at my first post in this thread, Find the absaloute max speed your CPU will run at and use dividers so that the ram is not a limiting factor, also find the absaloute fastest speed your ram will run at.

Now 12* 233mhz would be good

10* 280mhz would have better performance, as the FSB will overclock the memory controller and your memory will be running at DDR560.

As for timings, loosen them to 3-4-4-8, this is very loose but should allow a good overclock, you can them tighten them up later.

Have a look on the web, to see what speeds others are getting with your ram.

There is no FSB on AMD64 platforms.
There's HTT and MemClk. And they're independent on most boards I've seen.

conzy

I know, as you can see earlier on in the thread i explained it, but it is still referred to as the FSB for handyness sake, and it has the same function as the fsb, but it communicates directly with memory, through the onboard memory controller, rather than through the memory controller on the northbridge in a "conventional" PC

Crap now thats just confused me... are they actually separate? The HTT affects the MemClk doesn't it? I thought the MemClk was the memory divider, and acts as a ratio of the HTT?

conzy

Basically at stock:

The HTT runs at 200mhz
The HTT Bus runs at 200mhz * 5 = 1000mhz (2000mhz double pumped)
The CPU Multiplier * 200mhz HTT(reference clock) = CPU speed

Now the memory speed is somehow linked to the multiplier, and thats why its bad if you dont use an integer Multiplier, because it makes the memory run at a different speed, Im not exactly sure how its calculated, but we dont need to know that:D

think its my ram holding me back (btw wont boot at 10 * 280 ) but will 12 * 233 no bother but any demand applications give a reset!

power is fine, chip can go to 3.2 no bother so I've heard!

recommend me a good set of 2gb (1*1gb memory chips) pin 184 for my BOard.

conzy

Some go to 3.2ghz but maybe yours wont, Also you have good ram and there is no need to jump to conclusions:D

Find the max speed of your ram by loosening the timings to 3-4-4-8 and lowering the multiplier, then start to raise the HTT

Then find the max speed of your CPU by running memory on a divider, when you hit a wall raise the vcore to 1.45 then to 1.5...............

Until you know the max speed of YOUR components there is no point going any further as we wont know whats holding you back.......

Just a quick question. How can you find out if your memory is buffered or not. I'm running this memory:

TwinMOS PC3200 DDR DIMMs 1024MB

I set the command rate from 2T to 1T all went fine, but i left the computer on over night and woke up to find it had been reseting itself (certain programs where open on the desktop that i usually close when i boot) I checked the event viewer and it was giving me this.

Save Dump: The computer has rebooted from a bugcheck. The bugcheck was: 0x1000000a (0xd96d4234, 0x00000002, 0x00000000, 0x804e5d78). A dump was saved in: C:\WINDOWS\Minidump\Mini040506-02.dmp.

From digging around i've found this to be a memory problem, and as the only change i've made was to set the command rate from 2T to 1T i changed it back and am now waiting for the computer to reboot itself again. Thats why i'm wondering does my RAM have the capability to do 1T and it needs to be RMA'd or is it unbuffered RAM? Where can i find this information?

L31mr0d

Ok so it turns out my memory is unbuffered? Can someone tell what kind of memory is buffered? and is it better, because i've found this OCZ RAM on Komplett, that €232 and yet is unbuffered?

OCZ 2048MB kit

see i cant flash the 6.65 version of the chipset drivers.i need to install these before i try to flash the bios ? it just coms up with a error missing some file ?


also found these 2 shop on ebay selling the chips asus are not the best in uk but you can buy them off there site in the us lol

Buffered memory has ECC (error checking) and is used in servers, it is actually slower than unbuffered memory.

Is your ram overclocked?? If its overclocked, it might not be able to handle 1T at higher than stock speeds.

You have to update to certain chipset drivers before you can flash to the latest bios using the ASUS update utility, I dont know which version you have to update to, but check the site;)

secret_squirrel

No offense claregalway but I think you are seriously risking your PC with the messing around you are doing.

Buying an off the shelf F-S pc was a huge mistake if you wanted to get into overclocking. You have already probably voided any warantee you might have.

Your really need to realise that 1 fúckup on your part will leave you with a very expensive paper weight. ARE you sure you are willing to risk that???

Flashing a custom corporate bios with a generic one is something I would hesitate to do and I've been building and modding PC's for years.

You need to be doubly sure that F-S used an ASUS board on your pc. Frankly I would have though it was a custom one.

I dont wish to sound elitist, but quite frankly you dont sound any where sure enough of yourself to be messing around. Just my 2c.

Yes we were all at your stage once but I think you're trying to run before you can walk.

conzy

Yeah, Claregalway did you make sure that the F-S Cmos is the same size as the ASUS one??

I think the ASUS one is 4mb, but google it;)

awhir

how will i find out what size it is and yes i am 100 percent it is a asus see it is not realy a f-s pc it was made by a pc mazine and fs built it if you get me.its was made for gaming.

ok here are some pic of my motherboard

conzy

Yup thats a ASUS A8N SLI if ever seen one:D

Follow the instructions on the website for flashing to the latest BIOS, if you cannot do it, Get ASUS to send you a CMOS chip

L31mr0d

Ok, sorry to change the subject again, but should my RAM support a timing of 1T? In my BIOS it says to only use a timing of 2T if you are using unbuffered RAM, but it doesn't say anything about what 1T is compatible with. Should unbuffered RAM work with a command rate timing of 1T.

L31mr0d

Ok i'm in the middle of testing how much my system will OC, going well so far, i'll post the specs when i'm finished.

Just wondering, to fully test if my system is stable, can i just run OCCT for 30mins, or do i also need to run 32 Super Pi, Prime95 and memtest? Which program is the best balance for reliability and time for testing.

BTW, how does 32MB super pi work? I mean it seems to just be a program for generating Pi to 32M places?

Think how much calculating PI to 2 places would make your brain hurt.

Calculating PI or prime numbers (Prime95) for huge accuracy/huge numbers is enough to stress even the best desktop cpu.

The great thing is that since they are essentially brute force calculations they will scale with the power of cpu's.

L31mr0d

ok so is 32M super pi just a performance benchmark then, i.e. it will execute faster on faster machines... will it read an error if i'm overclocking my RAM or CPU too much?

secret_squirrel

L31mr0d wrote:

Well it could be used as one but you have got the wrong end of the stick.

Its a stress test, that thrashes certain sections of the cpu to get results.

My faster comment that seems to have mislead you is that since both the search for PI and Primes are essentially never ending that it will still be a stress test no matter what the cpu because you would just be looking for more and more decimal places or bigger and bigger primes.

What they essentially do is get the cpu nice and toasty since the hotter a cpu runs the more prone to an error it will be, since resistance increases with temperature. (very basic and just the tip of the semiconductor ice berg - pardon the pun)


As for memory tests - it depends on exact way the test is structured, but in the main I would expect both of them to be mainly CPU tests rather than Memory tests. That is if they are written in the most efficient way. They could have been deliberately written to give the memory a work out too.

For instance Prime95 has several tests that stress different bits of the CPU.

awhir

well if your cpu is under to much pressure yes i presume

dont call me right just a guess.

L31mr0d

how will these errors be manifest? will it just crash out? From reading around, it doesn't look like this program was meant for benching or stress testing, does it actually have the facility to let me know what error happened and where? Is it better than, say, memtest?

awhir
