Need some advice on what to do next...

post #1 of 7
Thread Starter 
Alright,

I started at 200 MHz FSB, stock voltage, upped the RAM voltage from 1.8 to 1.95 because of everything i've read on that OCZ Gold Series Ram. (PC5400).

No i'm up to 245 FSB, +50 mV on the Vcore. But it seems like everything I do causes instability.

I'm just confused as to what to do with the RAM timing. Currently it's 4-4-4-12.

What should my next steps be????

What is the current clock speed of the RAM? You might need to knock it down a bit.

If you can, show us the main screen adn the memory tab of CPU-Z

First I will assume that you’re FSB : DRAM ratio is set into a direct conjunction mode (i.e. 1:1).

If this is indeed the case, this states that your system memory will be operating at 245 x 2 = 490MHz Dual Data Rate (DDR2).

Your system memory, defined as PC5400, is a 667.1MHz - 675.8MHz ROF part (Rated Operating Frequency). Therefore is capable of operating with a bus of ~333MHz without breaching its operating limitations. There should not be a problem with your memory to that range, if it is given the correct amount of voltage.

Considering your Processing Unit being a Pentium 4, it is unlikely that you will be able to reach 333MHz on a standard cooling solution (i.e. Air Cooling/Water). You can therefore select a divider to force the memory to run at a frequency near its native frequency, to increase overall system bandwidth between system components.

As for latency pause periods (latency timings). These are not extremely important in regards to Intel computers system running under the Netburst architecture. Therefore ascertain the highest clock frequency that you are able to accomplish with your modules. Once that objective has been completed I suggest you then use a Trail and Error to ascertain the lowest, stable, memory timings for your memory modules.

If you wish to ascertain better memory timings you can increase the VDIMM to compensate for the reduction in stability caused by the reduced latencies. Be warned that increasing the VDIMM of memory modules will increase the temperature of them, so be wary.

Alright, well first off thank-you for your reply. I'm actually stuck at work right now and away from the house so I cant get screen shots of anything right now. Last night I had a lot of trouble and ended up resetting the Bios at the end of it all; planning on starting fresh tonight.

When I start, is it best to set the RAM to the LOOSEST possible settings? I.E. 5-5-5-15 (I think 6-6-6-15 is possible as well ??) and then increase the FSB until the CPU stops responding to Vcore increases, THEN tighten the RAM timing to get the best performance??? Stock voltage is 1.8 V. When should I up that ? And How high should I go? I have heard people running that RAM at 2.1 V but in my bios anything about 1.95 V the value flashes (not sure why...contacting MSI for support...any ideas???)

Also: How many Vcore increases should I do (in a row) before quitting? I mean if I increase the FSB to 225 (+ 50 mV from stock) and it locks the system....should I just continue to increase Vcore until I reach either 65C or 1.525 V ??

The lowest possible memory timing setting is the best performing. However, it also the least stable, depending on clock frequency, voltage, and temperature.

Temperature affects components by affecting the resistance and resistivty. This therefore has an impact on the remaining physics factors regarding the component. Therefore, the lowest voltage, or coolest conditions, are the most practical for memory. Granted memory running on DDR2 CAN (does not state WILL) withstand the up most of 120 degrees Celsius (T junction).

Increasing the CPU clock frequency (via increasing the system bus) and then increasing VCORE when the system fails the POST procedure is the average way of overclocking the system.

Be wary that you must also lock all outside frequencies to prevent them increasing in conjunction.
This means you must lock the PCI-E/PCI/S-ATA-I-II (if possible) frequencies to prevent clock increasment with the CPU.

Most motherboards are unable to engage a S-ATA clock lock. Therefore on your Pentium 4, you may be limited to the up most of 250MHz FSB (which is where S-ATA-I runs out of range). If this occurs system errors will occur, and corruption will be detected within system files. S-ATA-II's range is approximately 500MHz.

2.1 volts may be fine for your memory modules. It depends upon the thermal conditions surrounding the modules, and the ability of the modules to transfer thermal energy away from them. I would assume this would be an acceptable setting. However, without knowing the thermal status within your computer I can not give you a full answer.

The memory voltage will flash and/or change colour, if the memory voltage is outside of the recommended value. This value you have selected can be set, however a warning will be demonstrated to make you aware of the issue.

You can increase the voltage as far as you wish, as long as the value does not exceed our recommended limitation of 1.525.

This value will vary per configuration, however we accept it as a decent cut off point.

Be aware that the higher you increase voltage, the less time your CPU will operate for.

As for temperature, yes I would suggest you try and keep it as low as possible. Below 60C would be recommended.

I JUST contacted MSI tech support and they told me that I cannot lock the PCI/SATA I or II frequencies. There is a lock for PCI-X but not for the others.

Is it still safe to overclock or should I just leave it at factory specs?

If it IS safe, how high can I clock without damaging the disk drives? (I have two 74 GB Raptors in Raid 0 as well as a 250 GB Western Digital and a 320 GB WD on SATA-II).

Thanks

I suggest that MSI stated to you that you can lock the PCI-E frequencies, as PCI-X is a totally different PCI interface system.

PCI-E and PCI clock locks are interfaced in parallel on most MSI boards. Therefore, hopefully, if you lock the PCI-E clock frequency the PCI clock will also lock in conjunction.

PCI-E Recommended Range 100.0MHz-110.0MHz
PCI Recommended Value 33.3MHz

I suggest you do not exceed these values, to prevent corruption to the hard drive files, and buffer overflows to hardware on these lanes.

If the PCI clock will not lock, you can still overclock your system. I would however suggest you download ClockGen. Do not use ClockGen to overclock, just use it to check the value of the PCI frequency. Do not let the PCI frequency breach 38MHz for safety. Your can therefore overclock to that point.

If your hard drives are running on a S-ATA-I port I suggest you run your overclock at around the 250FSB mark. If they are connected to a S-ATA-II port you can go as high as you wish, until around 500FSB (which you will not obtain).
