Intro, if you want, you can ignore this
In Mid 2004 I built my rig which consisted of an IC7-G motherboard, P4 2.8C, 120GB HDD, and some high quality corsair PC4000, Twinx1024 memory. The memory cost around $260 when I bought it, quite expensive considering that the processor was cheaper than it. I purchased this memory with the intent to overclock this system, because you know, this board and processor combination were not only mature but very good overclockers.
So I assemble the system and I overclock it and limits to 3.2, eventually I figure out it's PSU related, so I got a new PSU and I was able to get my system stable at 3.5GHZ/250MHZ FSB, which is the exact speed of my memory modules, so I was relatively satisfied (I heard about 3.6GHZ overclocks..).
I was told that I had a respectable overclock and that I should quit whining cause others had less of an overclock. Some time earlier this year I tried again but realized I was still at the same fate I was at 2 years ago, though this time my max FSB (POST) was 262MHZ, not 255 as it was back in '04, likely due to a bios update. Keep in mind that I did everything I could to allow for higher clocks but nothing allowed for them, this included voltages, chipset settings, memory dividers, agp/pci locks, disabling chipset 'enhancement' features etc. Hmmm.
So I ask around these forums and I get nothing as to why it's like this, the same old 'it's respectable overclock, yada yada yada', reason. The reason I was so intent on being able to overclock some more is because I knew this CPU wasn't being pushed near it's limits since it was running fairly cool, so cold that earlier this year I underclocked it but the temps didn't actually improve.
So last week I'm reading up on overclocks on the P4/875p combo with all the boards, seeing how high people got. I RMA'ed my motherboard a few weeks ago prior to reading up on this (for unrelated reasons) and recieved the board this week. So with the knowledge of 300MHZ FSB overclocks on 2.4Cs and a new board, I thought that I should be able to do at least 270MHZ. So I overclocked the new board yesterday and what do I find? I get the exact same overclocks as I was getting prior to the RMA. Only difference from earlier this year and '04 is that I have an internal PC speaker which made an audible continuous beep. Hmmm
So last night close to 1am, I stumble upon this site Text and read up on the 875p fiasco. Sadly, I never knew about this article and I have to wonder how many on this forum DID know about it or anything related to it..
So, this afternoon I take a Kingston 512MB PC3200 module I recently purchased for another system I built recently (elcheapo system), pop out my Cosair PC4000 modules out of my machine, and pop in the PC3200 module.
I boot up and everything works, as expected. So I overclock and get back to the dreaded 262/264 barrier where once I got to 264, I got a long beep from the system (wasn't audible in '04 as I didn't have an internal PC speaker then). By now I have the memory divider to 3:2 and I'm getting ready to cross the threshold, and what do I find? IT BOOTS! Incredulous!
So I keep overclocking higher and higher and what do I find? It turns out, my system now posts at a whopping 282MHZ FSB, thats 3.9GHZ!
I went from a limit of 3.66, close to what the reviewer said in the link provided, to posting at 3.948MHZ!
Now I'm pissed, because I just realized that the reason I was never achieving the clocks I so longed for was because of the part I bought to achieve those clocks!!!!
:| :laugh: :| I'm not sure if I should be happy or pissed. Sighs, I guess I should be spending the rest of my time to find out my max stable overclock and how to sell this memory.
