Hi, With my new gfx HD 6770 i get 30 fps in all game. Here is some benchmarking in my rig:

Dragon age: origin: 40fps (16x AF) max: 63fps
COD: modern warfare2: 80fps (4x AA) max 130fps
Crysis: 30fps (4x AA)
Witcher 2: 15fps (Ultra) max: 21fps
Fable 3: 30fps(sometime drop to 22fps) max: 31fps
Farcry 2: 60fps max: 96fps

Is these fps is ok for my rig?

I use 1280x1024 res at maximum setting in all game. My cpu is Pentium Dual-core E5400 @2.7Ghz (stock). My ram is 4gb(2x2gb) @ 800Mhz. Mobo is g41m-es2l and my psu is thermaltake TR2 RX- 450W.

I see gaming graphic chart in Tomsharware where HD 6770/5770 get higher fps than mine. I benchmark with FRAPS.

Do i need some few tweak for my cpu or not?

The benchmarks are done with a super high end CPU
that is why you were shy, look into overclocking a bit
3.0-3.6 GHZ will add a lot of frames your board is decent for OC'ing
I was using an e5300 and my jump in frames from 2.5 to 3.6 was massive at 1920x1080 (4.0 not so much)
so you will see a ton more frames at your lower resolution

Then what if i overclock my cpu to 3.2Ghz? My multiplier is lock to 13.5x. I have to rise up the bus from 200Mhz. Will i do it from Bios or Gigabyte easytune6? Actually i never overclock cpu. So what bus do i set that is stable?

And also how long my cpu will last if i overclock? Its 1.5 year older. I cant buy another cpu within 2 or 3 years. So i need a safe overclock.

What type of decent cooler can be found under 40-50$? I see Hyper 212+ is a good cooler in forum. Will i use it or use another good brand?

You want to use the BIOS.

This should be your first stop.
Core2 Overclocking Guide
http://www.tomshardware.co.uk/forum/259899-11-core-over...

Next stop should be Shadow's Gigabyte motherboard OC guide:
http://www.tomshardware.co.uk/forum/page-245679_11_0.ht...
It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar. A G41 will have fewer available settings.

Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier from AUTO to 2.00 if it is available or 2.4 if 2.0 is not available. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 266 MHz, your memory clock should be at 533 MHz (2.0 RAM multiplier) or about 640 MHz (2.40 mult.) and your core speed will be almost 3.6 GHz.

You may be able to push the core speed higher, but 3.6 GHz should be relatively easy to reach.

Don't try to OC the memory. What little performance gain that you might get will not be worth any loss of stability. We talk about that here:
http://www.tomshardware.com/forum/251715-29-ratio-myth

As long as you stay inside Intel's recommended voltage (1.45 volts) and temperature (under 70 C) limits, short of a random failure, the CPU chip will become totally obsolete long before it dies from any overclock effects.

The Hiper 212+ is a very popular cooler because it works well and doesn't cost much. You would need to spend about twice as much to get significantly better cooling.

The G41 is an economy chipset with a limited FSB freq - about 350 - 360 MHz. I have an E6500 (same basic chip as yours except smaller cache) running at 3.66 GHz (333 X 11) in a G'byte G41m-ES2L with a mediocre by today's standards ACF7P cooler. It is stable at 3.87 GHz, but I do not need the extra performance.

Look like overclocking is a lots of trouble. Not so easy as i thought. How higher frame rate i will get if oc to 3.2Ghz or 3.6Ghz in the game i listed above?

Will i get extra 8-10fps or less? If i only get 4/5fps more after overclock then i think its useless to overclock for me.

I just got hyper 212+ cpu cooler 2 days ago. I tried to overclock my cpu, but bios automatically reset all setting to default. When i open MB intelligent Tweaker(M.I.T.) in bios, it said last setting is not coincide.

I set clock speed to 3.24Ghz(240 x 13.5), SPD to 2.66c(2.00/2.4 is not available) CPU Vcore to 1.28750V & DRAM voltage to 1.800V. I set Cpu Vcore to 1.3000V but no work. Bios auto reset all value. I dont know where did i wrong. Here is my voltage setting by default:

CPU Vcore 1.28750V [Auto]
CPU Termination 1.200V [Auto]
CPU Reference 0.805V [Auto]
DRAM Voltage 1.800V [Auto]

What should i change there? Is there any things else to change?

My memory frequency is 800 and set at 800 and timings is 5-5-5-18. FSB:D RAM ratio is 1:2. Please give me a detail setting cause this is my first time overclock. If you need more info about my bios, just let me know, i will post.

Finally I get rid of the problem by updating bios. Just older bios reset after overclock. Updating to new bios solve my oc problem.

Now i oc my cpu to 3.6Ghz. Vcore is set to auto. So voltage is around 1.344v/1.36v. My cpu avg. temp is 56C at full load and highest to 63C at Full load. It is stable after 7 hours prime95 stress test. So, do i need to set cpu voltage manually or it is fine on Auto?

EIST should be enabled, not so much for power saving but to reduce the thermal load when idle. If your overclock is not stable with EIST disabled, your overclock is not stable PERIOD.

I have several overclocked Core2 systems. All are 24 hour P95 stable with SpeedStep enabled.

I see E5200 cpu also drop voltage at full load and increase at no load in Tom's Hardware cpu overclocking guide.

Quote:
Knowing that the Pentium E5200 should reach at least 3.60 GHz with air cooling, we first tried the next-higher Intel-standard FSB of 266 MHz (FSB-1066). The system booted normally and passed a 40-minute stress test using Prime95 v25.8 build 4. CPU-Z reported core voltage dropping to 1.38V under load however, so we increased the BIOS setting “CPU Voltage (V)” (second screenshot above) to 1.4132 volts. This resulted in 1.424 volts at idle and 1.408 volts at full load.


This is the link.

So i think my cpu voltage are good. What say you?

Hi, and how about the new fps rates? im asking becose i have a e5200 and if you get a good results maybe i'll try to oc to 3.6 like you.

You will get a lot more FPS at 3600 vs the current clock depending on the GPU
got up to 12 or frames more with my 5770 depending on the game.

As Spentshells says, you will get 12 or more, depending on game. But it is so smoother than default clock.

i see, but i'm asking because i had oced it to 3.33 and all the games I've played did well. And if i'm planning to oc to 3.6 i would have to buy a new heatsink and cooler and the gain should justify the expense.

Yes I would recommend spending money on a TX3 or hyper 101i these should cost up to 20 dollars. Hyper 101 cools like a arctic freezer pro 7 which got me to 4 GHZ with that chip.

I see, so.. Thanks for the info. Ill keep this in mind. but what do you think about hyper 212?? because maybe i will try to push it up to 4ghz.

And one more thing, i hate that the TX3 uses push pins which are a pain to install, the another day i was hours trying to install the stock cooler. Maybe this is the price that i need to pay to use a more simple system that avoid me to removes the mother from the case.. NVM

I use hyper 212pluse and cpu frequency @ 3.6Ghz. 56c temp is average and 63c is highest. So i think its not that good @ 4ghz. But good for 3.6ghz at low price.

About install the hyper 212+, you have to remove your motherboard from case and set screw from both side of motherboard. It take more time from push pin but easy to install. You have to figure it out how to install or watch youtube video. User's manual is not that good.

Hyper 212 is a great cooler but is more than you need but why not for an extra 5-7 bucks mind you it is a lot bigger than the coolers I suggested
