Hi all,

First off, I'm a TOTAL newbie at overclocking (actually, make that a total newbie PERIOD :rolleyes:!) and I just want to get some clarifications before I go ahead with this system I'm planning to build. [I'm on a VERY tight budget!]

This is the system I have in mind as far as components go:

Processor: Core2Duo e6300 @ 1.86 GHz (Allendale)

MoBo: ASUS P5B or ASUS P5B-E

Memory: Transcend DDR2 667MHz
(CAS 5, v@1.8v)

[This is the memory that is available to me. At the most, I might be able to get Kingston memory but it might not be available. This sucks I know, but there's not too much of an option left to me really]

Graphics: BFG Tech 7600GT 256MB(OC)

I've been doing a bit of reading and research about overclocking and this is my question:

[NOTE:All cooling will have to be done with the stock HSF that comes with the processor! Cannot afford any aftermarket cooling right now!]

If I go with the vanilla P5B, according to the manual, the FSB maxes out at 400MHZ. Keeping the RAM ratio at 1:1 and the multiplier at a default of 7 for the e6300, theoretically I should be able to get a core speed of 2331 MHz=2.3GHz right? This ofcourse will have to be adjusted with the vCORE settings but lets assume for the moment that the vCORE is not a problem. My question is this: assuming that the RAM ratio is kept at 1:1 (DDR2 667MHz = 333MHz), and that the max I will go to on the FSB of the e6300 is 333MHz (from 266MHz), will I have to do any adjustments to the vDIMM settings? I would really like to avoid mucking about with the memory because it is 'value' (read cheap) RAM and I would like to avoid making any adjustments with the vDIMM. I've assumed that because it is DDR2 667Mhz (FSB=333MHz), it will be running underclocked at the core FSB of 266MHz and this assumption makes me believe that I can overclock to its rated FSB of 333MHz without making any adjustments to the voltage being supplied to it. (I might be mistaken, but from what I understood from this site, the RAM supports a max. voltage of 1.9v). If you're still here and reading this, what I REALLY want to know is this:

From what I've explained above, will the vanilla P5B do for my requirements or should I go in for the P5B-E which goes up to an FSB of 650 MHz and by all accounts overclocks better than the plain P5B? I would really like to avoid going in for the P5B-Deluxe. I don't really need all the bells and whistles it comes with and more importantly compared to my options, its way too expensive. Just to give you a rough idea, the best price I got for the Deluxe where I live translates to about 260$ USD when it's going on Newegg for 182$!!

Although getting to 2.3GHz from 1.8GHz seems very sweet to me, any tips or suggestions to get further will obviously be welcome! :)

Any help will be much appreciated!!!

EDIT: Will also have a couple of 120 GB @7200 rpm Seagate HDD's and one Samsung/Lite-On DVD writer that will complete the system. Will be running all this on an ANTEC SP 400W.

Given the constraints posted by (tight budget, stock cooler and "value" RAM), the sensible goal is a modest, stable overclock rather than chasing maximum clocks. A motherboard with cleaner power delivery and finer BIOS voltage/FSB controls will make that process easier and more forgiving; that is the point was making. Also, 's recommendation to improve thermal interface material is a high-return, low-cost step worth doing before any tuning.

A practical tuning workflow that fits a budget build:

  • Update the board BIOS first so you have the latest stability and voltage options.
  • Restore safe BIOS defaults, then make changes in small increments. Increase the FSB a little at a time rather than big jumps.
  • Keep the memory running at or below its rated stress by using a memory divider or looser timings rather than pushing its voltage.
  • Disable power-saving/cpu-throttle features while testing so results are consistent, then re-enable once stable.
  • Raise core voltage only in small steps if needed, while constantly watching temperatures and system behavior.

Stability checks and troubleshooting:

  • Use a CPU stress test to catch compute-instability and a separate memory tester to confirm RAM reliability.
  • Monitor core and VRM temperatures closely; VRM overheating is a common limit on budget boards and with stock cooling.
  • Symptoms like freezes, reboots, or memory errors call for backing off the FSB, loosening memory timings, or a small voltage bump. If VRMs get hot or temps approach safe operating limits, stop and improve cooling.

Final tradeoffs: with the stock cooler and inexpensive memory, aim for safe, repeatable gains. If the pricier board only adds a modest premium it usually pays off by giving more BIOS flexibility and better voltage regulation. Good thermal paste and improved case airflow are inexpensive upgrades that extend headroom; an aftermarket cooler is the next best upgrade for any further overclocking.

I think spending a bit more now would be better, buying to P5B-E, instead of buying the cheaper one. From 1.8 to 2.3 is a lot of gain and would show when you're gaming or just using it at all. Spend more now! The price difference is only around $30 to $50 (US) from what i've looked at... In addition, the core 2s were made for overclocking, so you dont have to worry about it getting toasted at a higher clock speed.

You should be fine, but increase alittle at a time to make sure that your(value RAM) can handle it. Invest in some quality thermal compound also, it will help keep the CPU cooler with the stock fan.
