Starting with BIOS overclocking.
Starting with BIOS overclocking.
H4VOC89:
Motherboard details: Asus P5E65 WS Evolution (with the newest BIOS update).
A great motherboard featuring an X48 chipset, offering BIOS voltage settings that cover GTL voltages. Back in the past, many boards lacked the capability for precise voltage tuning, limiting overclocking potential.
Your board offers excellent overclocking opportunities.

Your 1333mhz RAM will be a challenge for overclocking.
Even though ASUS claims support up to 1600mhz memory, it can handle 1800mhz overclocking. This means you can boost your memory speed to achieve higher FSB stability, though success depends on proper tuning.
Does this clarify things or cause confusion?
???H4VOC89, Where have you been?
I’m sure this wasn’t meant as a joke!
If you already have what you need, just let me know and I’ll stop here.
It's quite accurate: when discussing juggling voltages, I assumed you meant CPU voltages. Would he or would he not be able to maintain memory speeds during overclocking? Could he not adjust the CPU and reset the memory frequency when it becomes too high?
That is quite accurate :O when you mentioned juggling voltages, I assumed you meant CPU voltages. Vcore, PLL, VTT, and GTL are all CPU voltages.
And the more you discuss, the more you seem to be coming across as a condescending figure?
I get what’s happening. I know that raising FSB affects certain parameters like PCIE frequency, HT link frequency, CPU/NB frequency, and RAM frequency. I get it. I’ve done it before. On my system, I can reset the memory frequency. I can keep my CPU OC unchanged and adjust my memory speed to a level closer to what it was originally, if needed. If it’s failing, that works. Still, I’m not sure you fully grasp what I was asking for. I know about FSB overclocking. As mentioned, I’ve done it myself before. I didn’t achieve stable FSB from 200 to 255 without closely monitoring all the frequencies.
I know he won’t be able to adjust the memory speed, but in my BIOS I have settings to choose from. If changing it pushes me into a range that causes failure, I can lower it slightly. It won’t be the precise number unless I have an exact FSB ratio, but I can estimate it.
I was still wondering why you believed I was mistaken in what I said. I have the ability in my BIOS to reset memory speed, don't you think? That was my point. I grasp what happens during FSB overclocking, and I know he can't increase the OC multiplier. However, I can track my memory speeds and adjust them to a lower setting so I can keep overclocking my CPU.
Haha, sorry for the quiet lately, I'm working on my school project and have a lot on my mind these days. It's not a joke at all, and I was really surprised by the number of replies. I've read all the posts and I'm truly grateful for the responses! 😊
Also, I'm from Sweden, Ryan6.
By the way, I know my motherboard can be upgraded with 1600mhz RAM, but I thought that was just a rumor. So I could only use one slot in each channel. I have 8GB (4x2GB) of 1600 RAM, but that would mean I could only use 4GB of it. I remember the specifications from the Asus homepage.
Additionally, I reside in Sweden and am Ryan6. By the way, I’m aware my motherboard supports upgrading to 1600mhz RAM, although I initially thought it might be (just a rumor). Therefore, I’m limited to using one slot per channel. I currently have 8GB (four 2GB modules) of 1600mhz RAM, which would restrict me to using only 4GB of that capacity. This aligns with the specifications I saw on the Asus website.
That’s disappointing! I had hoped you were based in the US, as I planned to send you some 2133mhz RAM and a CPU cooler. However, the previous international shipment cost me significantly more than expected. Sorry about that.
Regarding memory, your setup wouldn’t require overclocking it as a fixed setting. You should configure it at something like 1333mhz, even though the RAM I used was capable of overclocking my Q9550 to 2000mhz. The motherboard and CPU wouldn’t recognize that speed, so manual adjustment is necessary. Set the bus speed to 445mhz for your Q9650s, applying a 9x multiplier (resulting in approximately 4005mhz or 4.005GHz).
The memory is sufficiently fast to handle increased bus speeds without issues, provided it’s rated for at least 1333mhz. If your RAM is only rated for 1333mhz and you push the bus too high, it will crash immediately. You need RAM that can sustain the higher speed.
One of my friends mentioned that 4GHz is manageable with the Q9650, thanks to its 9x multiplier. Starting at 472mhz with a 9x multiplier gives you around 4248mhz, which is similar to what I achieved overclocking the Q9550 using its 8.5x setting (see screenshot, multiplier listed as 8.5 and bus speed around 470).
That’s all the info you need. Your task is to master adjusting voltages—voltage, Vcore, PLD, VTT, GTL, and related settings. I’ve already downloaded and verified your motherboard manual, and you have the necessary BIOS tools for voltage adjustments.
Back in the era of 775-socket motherboards, there were a few exceptional models for overclocking. The extent of overclocking depended largely on the BIOS’s voltage adjustment options available. You’ve got a solid one!
The numbers I shared were achieved using air cooling. I used a Xigmatek S1283, mounted with two 120mm 1900rpm fans at 110cfm. The Xigmatek Gaia is an upgraded version of the S1283 and would still work well if you can find one.
Unfortunately, Amazon is requesting a Noctua NH-D14 instead, which would be cheaper and doesn’t require extra fans.
For a 4GB RAM upgrade, consider using only the primary slots and 2GB modules.
Overclocking an Intel 775 Core 2 Quad to the 4ghz and higher range is a complex process, anyone who has done it knows! When I mention it brought me back to Overclocking 101, I’m not making a joke! The main hurdle was understanding all the voltages and how they interact, so it’s wise to jot down your precise settings as you experiment. You’ll need this record to see what works and what doesn’t. Often I came close but had to restart, and there were times I felt like giving up for a lower speed, but I stayed focused until I consistently hit 4ghz. I assure you, achieving a stable 4ghz is an incredible sense of achievement and well worth the effort! I also say that if you can conquer core 2 quad overclocking, future attempts with newer processors will be much easier!
First of all thank you very much for that offer to send me the stuff, much appreciated Ryan!
I begin to understand what you are saying about the memory part of the overclocking, i guess its like having a type of headroom with the "more capable ram".
Ill see what i can find in terms of parts, the budet i pretty low right now
😛
But if i can get my hands on a cooler and some higher capable memory i'll definitely let you guys know. I Also know that to learn something like this, i will only learn more when i push myself and when bigger obstacles are in my way to solve. On the other hand, as as for now i guess i can only tinker with the stuff i have and hope i will gain as much knowledge as i can from what i have to work with. That said, what is the optimal goal to aim for in this case with what i have?
Thanks in advance!
