My first post on these forums but I have been reading them everyday for the past two weeks. I was wondering if I could get a bit of help on my timings. I am very new to overclocking and have been doing a ton of reading. Been trying all the settings of the people that have posted with a simliar setup but I cannot get my fsb above 247 without prime95 erroring. Could anyone please give me some pointers? I would be very thankful.
try idle cycle of 16
try drive strength of 7 and data drive strenght of 1 on bios 510-2
tras of 6
what mobo you on? and what voltage you giving the vdimm?Quote:

you could be maxing out the cpu...also make sure the htt multi is 3x
EDIT: i see your htt multi is 4x....move it to 3x and that should make all the difference in the world
MB is in my sig, DFI LANPARTY NF4 SLI-DR.Quote:

I have a XP-120 with a 120mm fan blowing towards the board. Since the HSF is over the memory I would assume that would be sufficent cooling for this system.
Does HTT mean LDT/FSB Frequency Ratio?

I got these settings from Socket 939 OC database HERE
When I use these settings and open up clockgen and move my FSB from 247 to 250 I can do a Super PI 1M. Before I was using Prime95 and getting errors. When I run Prime95 now I get FATAL ERROR: Rounding was 0.5, expected less than 0.4. Hardware failure deteceted, consult stress.txt file. Exectution halted.
So prime95 fails but super pi works....
ill almost guarantee is the htt multi...yes its LDT/FSB ratio in bios....put it at 3x and you should see 250mhz at 3.3v......Quote:

Ran a 3dmark 03 and it locked up my stem at 250.
cpu voltage is a bit high...i can do 2850mhz on 1.52v with my SD 3700Quote:

we are just worried about getting the ram working right as of now then we can tweak the cpu....if you max the ram at say 265 then ill help you with a high htt like 320 and a mem divider...so just to rule out the cpu lower the voltage and get it stable..i think thats whats erroring out now. 1.59v is much high for a SD 3700 at only 2.7ghzQuote:

lol i did :p:Quote:

Question....
Is 250x9 and a 4x HTT not good?
Is there anything I can do to get my core speeds past the 2700 mark?
Teecee: the best way of finding it out is by trying it out yourself ;).
DFI NF4 Ultra series users
Ø Use series 414, 510, or newer BIOS’
Ø Ensure proper RAM cooling with active fans dedicated to memory modules.
Ø Do not run >3.5v into your modules as this is in most cases counterproductive to your overclocking goals, and also voids your warranty.
Ø When flashing motherboard BIOS use the following sequence
1) Reboot, enter BIOS, Set vDIMM in BIOS to 2.8v and manually set timing to CAS 2.5, tRP to 3, tRCD to 3, tRAS to 8, tRC to 11, and tRFC to 15, set FSB to 200Mhz. Save/Exit.
2) Reboot and wait until MB has passed POST test and is past the BIOS report screen.
3) Turn off power to the motherboard
3b) If you have jp17 in the 2-3 position (5v position), return jp17 jumper to the 1-2 position (3.3v position)
4) Clear BIOS via CMOS reset jumper
5) Re-apply power, boot, flash your BIOS.
6) After BIOS has successfully flashed (make sure the flash has completed before rebooting!!) reboot
6b) If you want to return to using the 2-3 position of jp17 (5V position), wait until MB has passed POST test and is past the BIOS report screen, then power down your system. After power is removed, move the jumper back to the 2-3 position.
7) Reboot and re-enter BIOS setup
8) Set RAM timings and voltages to your desired settings, keeping in mind rated timings etc…
Ø When attempting to use the 5v memory jumper setting (jp17 position 2-3) use the following sequence:
1) Reboot, enter BIOS, Set vDIMM in BIOS to 2.8v and manually set timing to CAS 2.5, trp to 3, trcd to 3, tras to 8, trc to 11, and trfc to 15, set FSB to 200Mhz. Save/Exit.
2) Reboot and wait until motherboard has passed POST test and is past the BIOS report screen.
3) Turn off power to the motherboard
4) Move the jp17 to the 2-3 position (5v position)
5) Re-apply power, boot, and re-enter BIOS setup
6) Set RAM timings and voltages to your desired settings, keeping in mind rated timings etc…
Ø When running jp17 for 2-3(>3.3v) operation, ensure proper cooling of the 5v MOSFET located near jp17. If this item overheats, there is suspicion that voltages fluctuate. Furthermore, it is recommend that every end user watches for vDIMM fluctuation both in bios and in windows. Any significant fluctuation which would be more than 0.03-0.05v would be considered potentially harmful.
Ø Run memory modules in yellow RAM slots 1 and 3.
Ø Don't set memory voltage higher than 200mV below the power rail to the memory (3.1V for 3.3V rail for example)
Ø When changing or swapping memory modules, be sure that the power to the DIMM slots is removed. This can be positively verified with a DMM. Alternate method is to verify that the vDIMM voltage LED that is located next to the yellow DIMM slot closest to the CPU is off (if it is on, there is voltage applied to the DIMM slots).
All Athlon 64 Platform users
Ø Do not exceed 3.5v for module operation, as stated above.
Ø Avoid frequent power cycling if this can be avoided. While this does not impact your warranty status, it would be beneficial to end users to protect their investments. Frequent power cycling is hard on all electrical components in your PC.
Ø Ensure proper RAM cooling with active fan(s) dedicated to memory modules. Simple touch test to ensure memory is cool to touch is a good and quick test to determine if your cooling is effective.
Ø If using a voltage booster appliance, ensure proper cooling to that device, as similar to the MOSFET on the DFI board. If the booster overheats, voltage instability or device failure could occur.
We hope this identification guide and setup recommendations are well received in the enthusiast's community. We regard each end user as an extremely valuable partner and wish to make your experiences positive and above expectations.

Oh come flashing bios doesn't need all this procedure ?
IS IT me or REDLINE 4000 is just 213$ now at MUSHKIN ?
no it's mushking..Quote:

oh well it's friday let's all have a few and kick back :toast:
it's also better to clear CMOS after you've flashed your bios. Not only clear CMOS before flashing.
You can clear it when you program the BIOS if you wish... ( /cc using DOS version)
Peace :toast:
This redline is made for my SD 3700+ .....nice low volts and with no burn-in...sticks are 1 day old.

Hopefully i can get some 255 24/7 action @ 3.2v after some burn-in :)
