E5300 overclockers club - Page 97

post #961 of 1688
Hello, I thank you all. Have been reading your thread for the last week, and getting an education in overclocking.

My target was to get my PC to play Bad Company 2, well.

I achieved 3.6 easily yet found the game played just as well at 3.25, or at least
I couldn't tell a difference.

Now I have a comfortable clock, I am reducing voltages and temp, without spending any coin.

This is what I have so far.

My PC specs are:

CPU: Intel Dual Core E5300 with GlacialTech Igloo CPU Cooler.
RAM: 4GB Transcend DDR2-800 (PC2 6400, 5-5-5-18)
Graphics: NVIDIA GeForce 9600GT
HD: 120GB Seagate 5400rpm, 500GB Western Digital 7200rpm
PSW: CHIEFTEC 420W
OS: Win7 Ultimate 64bit

My goal is to get it around 3.5Ghz if possible.
I am currently running safely at 231x13 @ 3.0Ghz but i can't push it more than 240x13 without instability problems.
I undercloacked my RAM so that it gives FSB : DRAM ratio at 3:4 (231:308 according to CPU-Z)
Increasing the CPU Voltage in steps of +0.0125, +0.025 or even +0.050 doesn't solve the blue screen crashes when running a prime95 Torture Test.
In BIOS there is no option to decrease the CPU Multiplier in order to try the settings ''omari79'' posted in the 1st page of this thread.

Maybe the Motherboard is limiting my OCing potential?
Any suggestions would be really appreciated.
welcome to the thread mate

as for your overclock, i have some questions that may help you out

1- what are your voltage reading in CPU Z when the CPU is ideal and when its running prime95 @ 3Ghz ?
2- what are your core temps readings when your CPU is running prime 95?

CPU Z Voltage when CPU is Idle = 1.120V
CPU Z Voltage when CPU is running prime95 @ 3Ghz = 1.248V

Max Core Temp when running prime95 = 54°C

As I keep experimenting, and reading, Ive gotten my ratio 1:1 on the FSB DRAM.
I now do have a noticeable increase in performance going up from 3.25ghz to 3.40ghz.

I was wondering two things. Why do I now actually see an appreciable FPS,( in game bench plus 3d mark), gain, with the 1:1 as opposed to the 3:4 i had it at before, and, as Im now over 1000 rated FSB, is that too much?

Preliminary 1hr prime 95 blend test show no problems, and heat is the same, during the test. I also did not increase voltages.

Thank you.

welcome to the thread mate

great overclock with a great voltage but the reasons for not noticing a performance increase between 3.25Ghz and 3.6Ghz in BF2 are..

1- the actual increase in CPU performance is only around 3-5%
2- BF 2 is a quad core optimized game so upgrading to a quad will give you a dramatic performance increase in this game

well your voltage is a bit high for 3Ghz but nothing to worry about and your core temp is fine so this leaves the memory

open CPU-Z then go to the memory tab and tell me whats the DRAM frequency reading is

welcome mate,

1- what is your DRAM speed @ 3:4?
2- The higher your FSB rating the better your CPU performs, for example i am running 1333 rated FSB and i would be running @ 1600+ rated FSB if i had a better MB

Hey thank you, and thanks for the welcome. Yes that jogged my mind from the study Ive been doing about BF2, and Ive also noticed, 60 fps, in it is the cap for me, even at idle screen.

Curious to me was @3.25 in 3d mark, when going to 3.4 form 3.25, I got only an improvement of 6. This I did with ram at 800, and 667, timings also, multiplier of 3.33 and 2.66, DRAM ratio's of 3:5 and 3:4, respectively.

However setting Ram @ 532 and timings, 2.00 multiplier, and 1:1 DRAM ratio, my 3.25 score went down, of course, but my 3.4 score increased by 300, over the previously mentioned tests @ 3.4.

Dont get me wrong, Im very happy, but the old plumber in me, wants to know why, lol. Old plumbers dont believe in gift horses, haha.

I will be trying to get another board to work this week, it's somewhat better than this one, as I can, set the CPU multiplier, and get away from that 13.
From what I read, that will get my rate FSB down, probably. Im correct, that this will be a good thing, yes?

If your FPS is caped @ 60FPS then you must have v-sync enabled, disabling it will remove the FPS cap but its not recommended since this will cause screen tearing

not sure about this but as a general rule DRAM:FSB ratio doesn't effect performance at all, however, faster DRAM speed does

No, the highest multiplier for the E5300 is 13 so when you buy a better board you can only decrease the multiplier but that is a good thing since this will allow you to increase the FSB even higher to reach the same speed you have and opposite to what you've red, higher FSB speed = higher CPU and system performance, for example

3.4Ghz (10x340) is faster than 3.4Ghz (13x262)

No, the highest multiplier for the E5300 is 13 so when you buy a better board you can only decrease the multiplier but that is a good thing since this will allow you to increase the FSB even higher to reach the same speed you have and opposite to what you've red, higher FSB speed = higher CPU and system performance, for example

3.4Ghz (10x340) is faster than 3.4Ghz (13x262)
Yes ok, so the rated FSB I see in CPUID is the FSB I am setting in bios, times 4?
It's nice to check my understanding of the studying, gets it clearer in my mind. Thank you.

So and the 800 Mhz the CPU itself has, that is what I am increasing, or the bridge. Southbridge is it, or both CPU and Bridge?

Sorry for the questions, I'm getting very interested in this, as it is opening up more to me than, just making my machine run faster.
