Anyone got bios screenshots of their overclocked GA-P35-DS3P?

sven007

Thanks again PangingJr, here's my memtest results, but i realised I have Performance Enhance set to Standard, so I'll change that to Turbo.


In the meantime I have hit problems. When restarting, I get a long beep and no graphics, although it is obviously booting into winXP 'cos I can hear it. So, I've had to start again, this time leaving EIST, C1E, TM2 and CPU Hyper Threading (why would you turn this off anyway?) ALL enabled, I can get up to 390 FSB, but as soon as I set it @ 400, it sort of double boots and resets the FSB back to Auto (333). I was also got a Checksum error message at one point, so I loaded up 'Optimised defaults' and I am back to running @333 FSB at the moment.
What are safe core temps for this CPU. When running Prime 95 @400 with the fan @ full speed I was getting about 60(ish) degrees C, which I assume is OK.
Not sure whether to try the beta bios at the moment until I've sorted other probs, and as you say, I definitely would NOT use @BIOS anyway.

Just noticed the image is too small. Don't know how to rectify that!!

PangingJr

can you give me all of your BIOS setting, like on my post #4 and post a bigger pic.
also, i've never seen any checksum error message with mine, you may want to clear CMOS and try again.

zaim

check my results guys... thank you for EVERYTHING!

PangingJr

you're welcome.

that's whole lot better than your previous attempts to overclock the system. i like that, i believed 3.6GHz is quite good enough, i would keep checking and control all the system temps for a while and see if they can be lowered another 5-7C or so.

zaim

yeah i'm gonna try re mounting the cpu heat sink... i found a 775 plate from another 3rd party cpu cooler which mounts behind the motherboard.. i believe will reduce a few degrees. but these qx6700's run hot as it is =(

PangingJr

you may want to try this...
try dropping FSB from 450 to 444 (444x8 3552MHz, 444x2.50 DDR2-1110MHz ),
leave rest of settings as they are, but drop CPU core voltage down, try 3-4 steps down first, and try boot Windows,
the overall performance should reduce a little, see if the CPU core temp drop to around 49-50C, if so, test stability of your system...
and try drop CPU core voltage down a little more...
the outcome may vary, depending on the CPU, mine can drop CPU core voltage quite a bit and system remains stable.

sven007

Right, here's the pic.

Reset cmos as u said and now back to stock. Will start over. I'll post my bios settings later when I've more time.
Thanks again.

PangingJr

so the BIOS is set just like this below, correct?

"set memory multi to 2.0x, the performance enhance to Turbo, DRAM timing to 4-4-4-12 with the rest to Auto, and DDR2 voltage to +0.3, which is 2.1V at its rated."

if not, then try the exactly setting first.
if yes, your momery modules has already has a low tRRD and tRTP settings, which is good. and don't change this value to lower values at this time.
but somehow the tRD (or Static tRead value which is same as the Performance Level in the Memset program) is still quite high (lower Performance Level value is better),
on my 400MHz x 8 = 3200MHz and similar DRAM timing settings and 1:1 DDR2-800MHz with the performance enhance is set to Turbo, the the Performance Level is only 7 (yours is 11).

the rest of the memory subtimings can be lowered a little bit if you prefered,
however, you may need to add more volts to DDR2 and retest your memory subsystem using memtest86+ program before Windows and Orthos in mode blend within Windows.

as of now, you can set the following values in BIOS, and try adjust the values... boot the system with them and test your memory...

DRAM Timing Selectable [Manual]

- CAS Latency Time [ 4 ]
- DRAM RAS# to CAS# Delay [ 4 ]
- DRAM RAS# Precharge [ 4 ]
- Precharge Delay (tRAS) [ 12 ] <=== first try 10

- ACT to ACT Delay (tRRD) [ 3 ]
- Bank WRITE to READ Delay [ 3 ]
- Write to Precharge Delay [ 6 ]
- Refresh to ACT Delay [ 42 ] <=== first try 35 (and then 30, 25)
- Read to Precharge Delay [ 3 ]
- tRD [ 11 ]
- tRD Phase Adjustment [ Auto ]

note-- after you adjusted the above values in BIOS you will be able to see the memory bandwidth increases, the number is at the left corner of the memtest86+ program,
and if you see the bandwidth, has been increased quite higher than before, this may be an indication that you may need to add more volts to DDR2 and/or MCH and sometimes CPU core too,
otherwise you will keep getting error while tesing your memory.

if the system can't boot or system hang up during memtesting, turn off your power supply switch, and clear CMOS.

sven007

Yes, they are now.

Your right , the 'Performance Enhance' was set to Standard at the time I first ran MemSet and took the screenshot, but I have since changed it to Turbo and the Performance Level is now at 6 or 7.

I now have to try and get the FSB back up to around 400MHz and then I'll have another go at the memory.
I have some questions for you re: Bios settings:-
1. Were you able to reach 400 FSB with CPU voltage set to Normal ?(Just wondered if it was possible ?)
2. Did you leave EIST, TM2 and C1E disabled all the time, or did you try enabling them later ? I have read elsewhere that some have successfully re-enabled them after overclock.
3. Did you have to explicitly set PCI Express Frequency to 100MHz at all.

BTW, I have just gone through your previous posts and it looks as though the answers to Q1 & 2 are yes, but just wanted to confirm.

Again, thanks v.much for your time and help.

PangingJr

you're welcome.

the answer on Q3 is, you can always try locking the PCI-e at 100MHz, however, i have already tried and tested both the Auto and 100MHz,
when the system's CPU Host Frequency of 400MHz and CPU Clock Ratio of 8 are set in BIOS and in use on my own system and another 3 system that have similar hardwares with mine,
the PCI-e Frequency setting in BIOS don't seem to matter whether it's set to Auto or 100MHz, the computer system's (this includes the PCI-e devices, PCI-e onboard devices) are stable.

however, please do know that your motherboard's chipset and Intel C2D 6750 aren't exactly the same as mine.

i think, in fact, all the hardwares/chips (in the Gigabyte P35-based motherboard and Intel C2D 6750) have never been created equal.

try yours out to see how it works, and what's best.

and when you are ready to try the CPU Host Frequency of 500MHz and above, then the PCI-e Frequency and its supply voltage setting in BIOS will be more important setting in your overclock,
and it's something that you will want to try and test the settings even more harder, there is always the chance that you can damage either the hardwares or Windows software system otherwise.

sven007,

here is another one for you, check it out when you can.

410 x 8 (CPU multi 6x and 8x 410MHz, CPU running at 2460MHz to 3280MHz),
4 x 1GB Memory multi 2.40x DDR2-984MHz 4-4-4-12, Performance Enhance: Extreme.
Windows XP x64.



CPU Clock Ratio [ 8 ]
CPU Host Clock Control [ Enabled ]
CPU Host Frequency (MHz) [ 410 ]
PCI Express Frequency (MHz) [ Auto ]

CPU M/T [ Enabled ]
CPU C1E [ Enabled ]
CPU EIST function [ Enabled ]
CPU TM2 [ Enabled ]
No-execute memory protect [ Enabled ]

System Voltage Control = Manual
DDR2 OverVoltage Control = 2.2V
PCI-E OverVoltage Control = Normal
FSB OverVoltage Control = Normal
(G)MCH OverVoltage Control = Normal
CPU OverVoltage Control = Normal

-----------------------------------

412 x 8 (CPU multi 6x and 8x 412MHz, CPU running at 2472MHz to 3296MHz),
4 x 1GB Memory multi 2.40x DDR2-989MHz 4-4-4-12, Performance Enhance: Extreme.








when the CPU OverVoltage Control in BIOS is set to Normal the CPU core voltage is equal to CPU Vid value, which is 1.27V for my E6750 processor.
i can still go higher like 416x8 but then the Static tRead value needs to be move up to 6 (from 5) and memory bandwidth will drop quite a bit.
so on my system 412x8 is top and best when setting the core voltage at Normal and also having the CPU C1E and CPU EIST functions to work properly.

PangingJr

compare these below (which has a more higher CPU clock speed and higher memory BUS) to the above results of the 412x8's memory read/write/copy and latency.

for these below, since a more higher than the normal core voltage is required due to higher CPU overclock,
the CPU C1E, EIST will no longer be functioning properly any more (CPU core voltage will not drop),
in this case you may want to disable the CPU functions in BIOS.

i think, in overall, the above 412x8's overclock is better,
unless you are going to overclock your system quite a bit more than this.

memory at CAS4


memory at CAS5

PangingJr

i might as well post it. i hope it might benefit you in some ways

check out this 412x8 and compare it to the above 412x8 results, which at the time had using stock memory timings.

read, write and copy throughput and latency itself are improved after i worked out with all the timings setting in BIOS.
the results came out not bad at all when considering this low voltage overclock.

Hi just wondering if any can advise me on how to proceed with overclocking my Q6600 on GA-P35-DS3P. I am a little out of my league and could do with some pointers.
