Welcome to the E5300 overclockers Club



Things you should know before overclocking:

1- the voltage requirement for each CPU may be different
2- the FSB limit of the CPU depends on the motherboard and on the CPU itself
3- always use a well ventilated case and a decent aftermarket cooler
4- decreasing the CPU multiplier will increase the CPU voltage required
5- the most important factors in increasing the CPU's performance (apart from increasing its speed) are (in order of importance):

A- FSB/DRAM ratio
B- DRAM timings
C- FSB speed

6- the maximum recommended voltage for the E5300 is 1.36v, anything above 1.36v will degrade your CPU and anything above 1.45v will heavily degrade it even if the temperatures are within the limit in both cases
7- the E5300 maximum thermal specification (CPU temperature) is 74.1C
8- CPU temperature IS NOT core temperature, the equation is:
CPU t = Core t - 10C
9- programs such as REAL TEMP, HW MONITOR or CORE TEMP show core temp AND NOT CPU temp
10- Ideal voltage doesn't damage your CPU even if it is above Intel's recommended, however, load voltage does
11- always use a quality PSU and not a cheap one
12- always fill in your complete system info by going to User CP -> add system, so me and other knowledgeable members can better help you

hope gives you some idea
,.. dont know if somebody will complaint since we already have E5xxx thread

yeah i know we have an E5xxx thread but as i said before i think its nice to have our own club


anyway, very nice overclock and very good load temps...did you go for a 4Ghz+? since you already have a good AM CPU HSF

Someone might come and flame you for opening this thread

nah only the newest batch of E5300 spec SLGTL supports VT and yes i don't care about flaming, what i am after here is for the E5300 owners to share their top speed and what settings they used to achieve and stabilize it

Glad someone made this thread because I just built a spare gaming comp 2 days ago and wanted to know about other peoples settings for this little jewel.

E5300 in an XFX 780i
Cooling = Xigmatek S963
Speed = 3900 Mhz
Multi = 13
FSB = 300
CPU v bios = 1.3825
CPU v ITB = 1.376
CPU v Windows = 1.368
IDLE Temp = 31c
LOAD Temp = 71c
Dram speed = 800mhz

very nice OC but i don't think that you will be able to reach 4Ghz if your load temp is 71C @ 3.9Ghz, to be more accurate, you can reasily reach 4Ghz but the Thermal spec of the E5300 is 74.1C which means that you start damaging your CPU if you exceed it and you are already pushing 71C @ 3.9Ghz

E5300 VT
Cooling = Xigmatek S1283 Red Scorpion
Speed = 3660Mhz
Multiplier = 11
FSB = 333Mhz
CPU v bios = 1.3625
CPU v windows = 1.34
CPU v Prime95 = 1.34
CPU termination = no idea
Idle temp = ~45c
Load temp = ~65C
MCH core v = default; 1.2v
DRAM speed = 800MHz

note i am actually running my e5200 @ 3.33 currently, but i'll swap it out when i get my 4890, CM 690, heatkiller 3.0 and MCP355. That should be within a couple of weeks.

strange you and i are running the E5300 at roughly the same speed...yet i am getting almost the same load and ideal temp as you and i am using the stock HSF


I though Xigmatek S1283 will let you reach 4Ghz + easily and with safe temps yet with your voltages and figures, you will be hitting The E5300 thermal spec at 3750Mhz or 3800Mhz max

You Bios v is 1.3625 but your v-drop is 1.34, i can achieve 3660Mhz with a v-drop of 1.31 and hit 3800Mhz with a v-drop of 1.34, are you sure you are not applying more voltage than needed?

yeah... i have a really crappy case. Thankfully, i'm getting my dream case (used CM 690 lol) soon, along with a heatkiller 3.0 and MCP355! 30c load temps here i come...

btw i did get to 4GHz unstably with 1.41v or something like that; my e5200 requires 1.4v just to get to 3.66 lol. I don't have the best of luck..

I'm really happy with mine.
I could do higher, but i don't really need to, as this is just in my secondary system.



Temp sensor is stuck @ 51C till it warms up & "unsticks" around 60C, but it doesn't really matter.

Cooling = TRUE w/ 2x Noctuas P12
Speed = 4008 MHz
Multiplier = 12
FSB = 334Mhz
CPU v bios = 1.4
CPU termination = forget; will edit later
MCH core v = forget; will edit later
DRAM speed = DDR2-1113

Hi guys and gals, nice to see this thread growing, but i have an extra request form E5300 owners

Please state

The following

1- Your CPU stepping, there are two, M0(old no VT-X but OC better) or R0 (new with VT-X but has less OC potential than M0)
2- state you CPU v reading in CPU-z before and after stress testing

I also created a separate thread for a problem i am having with pushing my E5300 Past 3.65GHz but i was wrong in doing so because i already founded this thread for this exact reason, so i am going to copy and past my problem and,

to the kind attention of this site's Moderator

Please delete or if you like move my thread titled Help me reach 3.75Ghz on my E5300 to this thread

Excellent clock omari.
if you dont mind me asking how do you have the ram setup? I beleive im running into a ram problem because my bios is slightly confusing. I have been unable to go over 270mhz fsb and I was wondering if you ran into this same issue. I tried the exact setting you used and it wouldnt post. Im using corsair dominator ram XMS2 and I know it is highly overclockable. my cpu handle 3.5ghz 270x13 just fine and that is only 1.29vcore in the bios. I have a excellent cooling system to my highest recorded temp using prime was 49c and my cpu fans were at 35% so I could crank them up and freeze it if needed.

but yes please get back to me about my ram. Does your bios give you control over the divider? my divider options are confusing, 1:1.00 , 1:1.25 , 1:1.50 , 1:1.75, 1:2.00. and thats pretty much it.

Also this being a 45nm cpu it runs quite cool if you want a damn good cooler go to tigerdirect and buy the Cool Master Hyper N520 its only like 30$ and cooling like the best, there is only a 3c margin between it and the famous ThermalTake 120

Thanks, I just put my E5300 rig together and it seems I did get a newer E5300 with VT. Thanks

the settings?

Multiplier 12.5
FSB 300
Bios CPU v 1.400
CPU-Z CPU v 1.34
prime95 CPU v 1.32
Ideal temp 45C
100% max load temp 68C
CPU Termination v 1.3
CPU Reference v AUTO
MCH (NB) v 1.4
I/O (SB) v 1.65
DRAM v 1.8
DRAM 800MHZ
Result: PASS

So i have a good Overclocker after all


i will revert back to 3.5Ghz or even 3Ghz because My GPU isn't worthy of such a great CPU (my CPU is bottlenecked by it @ even 2.6):swearing:

so then
oh wow, that's pretty much exactly the settings i used to have my e5200 at... what exactly is the effect of CPU termination/ref?

first

Your ram is PC2-8500 which is operates at 1066DDR2 and yes they overclock well, so i don't think that the problem is your ram

also, you got a good cooler so you are set for 3.8Ghz+ speeds

now

Some rules you need to follow when Overclocking

1- find your FSB wall (put your CPU multiplier to 6x and start raising the FSB slowly starting from 200MHZ and reboot in 10mhz-5mhz instruments, and you need to do that while keeping an eye on your ram speed so it never exceeds its speed spec, so do that until you find your exact FSB wall (mine starts past 340Mhz) you will know when your CPU hits the FSB wall because it won't boot until you clear the CMOS or you will have a multiple-phase booting like mine and your CPU will boot @ stock settings

2- Divider setup is not important as long as you keep you ram within it's voltage and speed specs, as you can see from my detailed speed posts, i only put the memory speed, but when i get back home i will give you the exact same latch and multiplier i am using but that won't be really helpful since my RAM operates @ 800Mhz so different latches and Multipliers apply to me

oh and never leave anything on auto, most motherboard tends to throw way more voltage than needed when you start overclocking, also, Disable all CPU power saving features in the bios until you stabilize you OC
