WPCREDIT tweaks for the A64

Well, I can set it to DDR400 in the bios but CPUZ still shows that it's running @ DDR333. When I change the mem setting from 166 -> 200 Mhz in the tweaker = instantly freezes.

Can you run the memory at 200 MHz using the 166 MHz ratio by upping the FSB to 240 Mhz using clockgen?

Yes, but no 3d-stability because AGP becomes too much for the poor 9800PRO. Prime with large FFT size is ok, though.

Bugger, I thought it may have been a mem limit on that board.

OK, try 183 Mhz mem frequency. With a 10x CPU multi that will give 11x memory multi (a little better than 12x with 6:5 ratio).

Failing that can you send me a WPCREDIT shot of PCI bus 0, device 24, function 2 (in 32 bit mode). They may have set something wierd in the CPU registers, but really I suspect some hardware limitation.

[IvanAndreevich]

OK will do tonight!

[IvanAndreevich]

Ah haven't tried the 183 ratio on the K8V - got rid of my K8V SE Deluxe for a K8N-E. Tweaker works perfectly on K8N-E.

Any settings suggestions for a gig of OCZ 3700EB on an Epox 8KDA3J?

Well a gig is going to be hard to hit high MHz with.

First try with 2T command rate set to enabled (need a CG stepping for this to work) and see how it goes.

I'm Prime and Memtest stable at 10 x 235 @ 3-3-2-8-1T with the normal settings. I'm actually Memtest stable much higher, but my CPU won't cooperate. I guess I'll have to experiment. The system locks when I get it wrong though, so I was just looking for suggestions with the 3700EB. The problem I see with this program is that you can't run Memtest in Windows, so how do you know the settings are truly stable?

Run prime95 with FFT sizes of 2048->4096 so only RAM is tested.

Drop the multi and use a super-high HTT and higher memory divider.

Well this program just keeps getting bettter. with version 3 it loads on startup and runs great on my SK8V / FX53

it also allowed me a #16 spot on pifast challenge.

CodeRed rocks

[overanxious]

This program rocks, but if you are new to this:
WHATEVER YOU DO:
do not put on "load at startup" until you have everything just as you want it. If you do this and use clockgen, you're golden Jerry!Golden!

[blass]

can you translate this please?? -->

[overanxious]

If your comp hangs up or freezes, you can reboot, go into bios, reset defaults, load windows, and BAM! The bad settings are there again. You then have to go into safe mode to fix it. If you know what you are doing, this is no prob, but a noob like me takes 45 mins (with had no "choose OS screen" to get to safe mode) and lots of worry before you correct it.

[LilGator]

Press F8 to get to Safe Mode

[overanxious]

Thanks, I knew that, but I had "choose OS" set at zero seconds, so I did not have any time allotted to push F8. I had to put in a non-system disk on startup, then eject it, THEN push F8.

OK, I've got 64Tweak, clockgen, ATITool, CPU-z all of the software.
I understand the overclocking concept and the equations, but...

Where are the $&#@ memory dividers?

Are they the ratios in Bios, and that is the only place you can change them? Or are they on 64tweak, and called something else? Is it automatic when setting frequency or refresh rate? I can't get the CPU/mem ratio lower than CPU/10, leaving me to believe I just have to set the divider to 10 now. Any help is appreciated.

I'd like to congrat CodeRed firstly
and...does any one know any tricks for my Hynix D5 chips(Corsair 4400 rev1.1)?
They are prety crapy on my ZNF-250,only 227error free with 2.8v 3-4-4-7....

Edit
And i have a CO stepping so no t2 for me....

I am a bit confused on how the A64 Tweaker Works and wut its for? I really would like to tweak my A64 3000+ and id like to figure out how to change the memory timings so that i can get more overclock out of my cpu. Can u pls briefly explain to me wut this program does and how to use. I greatly appreciate it. Thank You.

A64 Tweaker is used to get the most out of your A64 by allowing you full control over all the useful memory settings. Originally I wrote this because my AN50R BIOS was so lacking in memory timing options. Only the latest DFI BIOS allows such fine control over your timing options (amazing how similar the new DFI BIOS options are to those inA64 Tweaker ).

The ultimate goal is to have the tightest memory timings at the highest possible freq ... a good target is 2-7-12-2-2-5-2-2-1-1 (really need BH5 for this), but dont worry if you cant hit such aggressive values. Start at something like 2-10-13-2-2-6-3-3-2-2 and work your way down testing at each step.

I used SuperPi and Pifast to test the effectiveness of each change to my timings. Its best to choose a proram that really stresses memory and gives good systematic results (3DMark is a pain to tune since it varies from run to run).

I cant tell everyone what their best timings will be since it varies from RAM module to module. Some sticks work with agressive vaues others do not and you are better off with relaxed timings and higher FSB. You have to test your own sticks and see what works best for you.

Attached is a screen shot showing the values I get the best 3DMark, SuperPi and PiFast times with. My Kingston BH5 sticks run up to 274-277 MHz with these settings @ 3.6V.

PS Dont worry about the extra Link settings in V0.5XT for now ... I am still working on it

[Fa1con]

So the lower the settings are in # value in A64 Tweaker the faster the memory is running, correct? Is there a way to like lock the memory for when i do overclocking so i can get a higher HTT?

[Fa1con]

Also i did those timings (the 2nd one) u told me today and my comp automatically restarted. Does that mean it is unstable i guess. If so is there other timings i can try?

[overanxious]

CodeRed:
I notice that on your screenshot you have a box that says,"Link parameters." I have 64tweaker 3.1 and don't have those settings. Is THIS where you set your timing dividers? Is it because of my MB is the Asus K8V SE that it's not showing these options? I asked where the ram dividers are earlier. I'm so close to dialling this thing in, but I need to know where they are. Are they the ratios in Bios, and that is the only place you can change them? Or are they on 64tweaker, and called something else? Is it automatic when setting frequency or refresh rate? I can't get the CPU/mem ratio lower than CPU/10, leaving me to believe I just have to set the divider to 10 now. Any help is appreciated.

Just wait, the picture is from a "beta".

Thats' a damn nice prog, I got +600Mb/s at sandra memtest at first try, following codered's advices !

I have a problem with cpu-z (1.23.1), it doesn't displat the model of my cpu (which is a newcastle).

You have to adjust each parameter at a time and test. Dont try for the tighest timings first go. What are your current timings?


@overanxious,
mem ratio is "MEM CLK Frequency".

[Fa1con]

My current timings or (defalut) w/e are 2.5-11-14-4-2-14-4-3-1-4. And also are there anything on the Configuration Parameters that i can do to help?
