It is only with the heart that one can see rightly; what is essential is invisible to the eye.

Mga Sirs, Patulong naman...

I've got a

Sempron 64 2800+ (stock at 1.6Ghz)
ASRock K8Upgrade nForce3 bios v P1.30 (Cool n Quiet disabled)
2 x 512mb DDR400 TwinMos
450w Task PSU
Inno3D 6600 OC

I OCed in BIOS (w/ stock HSF) to 2.4Ghz

When I check System Properties & CPU-Z lumalabas 2.4Ghz nga
but after playing for a while or pag iniwan ko lang bukas bumabalik sa 1.6Ghz

With aircon off, my temps are:
MoBo 41c
CPU   41c

With aircon on, about minus 5 to 10c from my temps above.

Never pa akong umabot sa 50c which I think I can eliminate
the possibiltiy of overheat issue.

Ano kaya ang problema? bat bumabalik from 2.4Ghz to 1.6Ghz
after a while?

Please help mga sirs.

Thanks in advance!

Hi guys!!

I've got a couple of questions with regards to overclocking my Athlon 64 2800+ (Clawhammer core).

Since I've got crappy PC3200 RAM, I can't overclock the RAM that much (even a 30Mhz OC messes up my system real bad), so I've hard to use dividers and drop the HT link speed. I've been able to reach a speed of 2.2GHz (245HTT x 900 w/ RAM at 200.5MHz) at stock cooling (and stock voltage) by increasing the FSB/LDT multiplier to around 245 and dropping HT link speed to 600Mhz plus dropping RAM speed to DDR333.

I was thinking of trying to see if I can overclock more by further reducing the HT link speed and reducing RAM speed more, in order to increase the FSB/LDT multiplier. My question is that will doing so, decrease system performance? Or does everything depend on how high I can get the HTT to be?

Thanks!!!

himuradrew try baka magwork kasi sakin ganito yung config ko eh ..

ginawa kong ddr333 yung ddr400 then htx3 25fsb yung nagawa kong stable and prime95 stable . 11mhz increase in my rams so 211mhz . generic lang din ram ko pero nilagyan ko ng copper cooler para sure then 2.7vdimm cpuv is 1.65 kinda high but its okie . ginawa kong 270fsb pero nagrestart 2.7vdimm hindi padin kaya hindi ko pa siya ginawang 2.8 maybe later pero stay muna ako sa 258fsb and yung ram ko is single 512 1x kaya niya 265fsb pero may error sa prime pero sa superpi wala .. so 258pinaka stable .. and nagrebios din ako para mas okie yung pagoverclocked ko msi k8neo fsr/lsr rebios to msi k8neo platinum

Hey! Overclocking have many ways... to be sure of: first, you must know the basic in overclocking; second, know the features of each peripherals what you have; third, you may use proper cooling and the last burn-in you toys (PC) step by step. Goodluck!
If you can do it right in the traning, you can do it right in real life.

Quick and dirty A64 clocking guide **UPDATE** X2 OC

Overclocking breaks things which you alone are resposible for, not AMD, not intel, not Nivida, not Ati, not xyz mobo maker. Proceed at your own risk.

this is a quick and dirty guide. I am aiming for simplicity since it's not all that complicated to OC A64's even for first timers. I am also aiming for safty so you don't kill anything so lower volts are advocated. Just good clean fun to get an FX or better from your budget chip.

VERY IMPORTANT to keep in mind at all times is hypertransport needs to be around 1000, meaning LDT x HTT (aka FSB) ~1000 or less.

Now we will Isolate then Consolidate.

What that means is you need to test three parts of the CPU subsystem (chipset, chip, and memory) to find max speeds of each.. Then combine them for some sort of optimal overclock.

ISOLATE
Don't forget to take notes.

1. Max HTT/FSB should be first ..*only works if motherboard has locks. Most A64 boards do today. Sata 1 and 2 are not locked on some nforce mobos use 3 and 4.
-set CPU multi to 6 or 7, this will take CPU out of equation
-set memory to SPD and 100, this will take memory out of equation
-Increase HTT/FSB up until you fail to boot or there abouts, back down 5%, (HTT * 0.95), this is your max safe HTT.

2. Max Chip capable
- Set multiplier to it's maxium
-Set vcore to 1.6 -1.65 for 130nm chips, 1.50-1.55 for 90nm chips
-Set mem to SPD and 100, this will take memory out of equation
-starting with HTT 200 raise in about 5Mhz increments up to boards max found earlier or until you start failing PRIME95 which will probably happen first..only give it 5 minutes max, that's good enough for now.
-At the point it starts failing within that 5 min time period, back down 5%, (CPU MHZ * 0.95), thats your max CPU speed, now test prime again at 95% for 12 hour for stable.
Prime 95 Link http://www.mersenne.org/freesoft.htm

3. Memory MAX

It depends what you want and type of mem you chose, LL or Bandwidth but must keep 1T (command rate) because A64 suffers big time with 2T.

-For high bandwidth set mem setting to 200 and 2.5-4-3-7 1 T and give it boards max volts, or for LL set mem setting to 200 and 2-2-2-7 1 T and give it boards max volts. (up to 2.9Vdimm is safe with all ram) ( Caution DFI/ABIT users -- do not exceed 3.0V unless you know what you are doing!!!)
-Set CPUs multi to 6-7, again to take it out of equation.
-Raise HTT up to boards max or until you start failing memtest86 test 5 and 6 http://www.memtest86.com/
-When you start failing memtest86 test 5 and 6, back down 5%, (HTT * 0.95), thats your max MEM speed.

CONSOLIDATE

The most important thing to keep in mind is CPU Speed is king. So now that you know your CPU speed from above, use it. Say it's Winchester 3000 and it's 2650Mhz prime stable and with it's 9 multiplier it needs 295 HTT to get there (9x295=2650)...NP right, but you got some value ram which only clocked to 210Mhz from your above testing. Well obviously you can't run the ram at 1:1 which would be 295Mhz, you must use a mem divider. You can use the memory divider (mem setting) to get as close as possible to your mem max found above.

This is the rough way to calculate IE close enough..

Memsetting setting
200 = HTT Mhz
183 = HTT x .90 = Mhz
166 = HTT x .83 = Mhz
150 = HTT x .75 = Mhz
133 = HTT x .66 = Mhz
100 = HTT x .50 = Mhz

What can my 210Mhz memory run in this config?
295 x .83 = 244 = not a chance
295 x .75 = 221 = not quite
295 x .66 = 195 Yes, but slow.

You have two choices, try and tighen timings and run 195 which is perfectly OK choice. Or Change CPU multiplier and start over. Ideally you want for max CPU and memory to coinside...Does'nt always work the way you want... My Ballistix below is 245Mhz stable but I'm running less for more CPU speed which always wins. You should too.


To help you along in the "consolidate" phase user Gogar has made a niffty script found here.
Just put in those maximuns found under the "isolate" phase and it will spit out the best choices.

After you go though these steps , take notes, you'll become more familiar with the whole tweaking process (learn by doing) and will be able to dial in better frequencies, timings, voltages, and faster too. But this should get you pretty close to safe and optimal speeds



UPDATE: Dual core CPU stability testing
X2 is not any different than a single processor overclocking but for volts and when prime testing CPU(s) for stability:

Volts should not exceed 1.45 for safe operation!

Prime95
1. Make two folders with Prime95
http://mersenne.org/gimps/p95v2413.zip

2. Starting two instances: Launch both instances from each folder and choose: torture test > small FFT's > click OK.

3. Next, launch taskmanager and set affinity of the first instance of prime to CPU 0 only. The other instance of prime to CPU 1 only.

what is HTT ? same as FSB ?

Are there any Sempron 64's na parang couterpart ng Venice na god steppings ? i heard some Sempron 2800 at 3100 reaching 2.6 to 2.7 ghz

at all Sempron 64's based on 90nm ? or yung may SSE3 lang ang based sa 90nm ? kasi may Sempron 64 na may SSE3 yun iba wala

i can't seem to find the multi controller, does it appear as cpu multiplier in the bios or is it labelled differently,

using the biostar 6100 m9 board w/ winchie 3200.  I wasable to run at 2.4 but had to bring up my vcore by .10 otherwise i can't even run super_pi without errors.

could it be my ram? using geil value (blue) dc channel stocked at 2,5-4-4-8.

and what's a safe heat reading on amd64s?

thanks

how do you overclock aside from using the bios? maliit lang kasi oc capability ng bios ko. 200mhz-232mhz lang. may utility ba or software na puwede magamit?

i was able to detect my pll but there are no buttons for clock gen to change the settings for fsb, multiplier etc...

am using a sempron 2600 @ 1.8ghz and an ecs k8m800-m2 mobo w/ a generic 512 ddr 400 memory... i know it's the cheapest... just wont be satisfied until i get the limit on this... i've oc'd all my computers to their limit and i wont let this one pass... hehe...

Hmmm...
Overclocking needs basic knowledge of some features of the mobo, memory, etc.

Distro does not recommend it that's also void your warranty. But, if you really does.. so, go on....

In MSI, to many option to OC that mobo.
but be sure that your adjustment does not exceed the limit which stated in the manuals... then same as the other computer parts.
If you can do it right in the traning, you can do it right in real life.
