Can I mix these two memory modules?

Ultimate Boot Disk on USB Stick, every neat lil tool you can think of,

 

The Windows Versions will crash windows sometimes, I prefer the direct Boot Environment Versions.

Thanks for the tips, all. Will definitely put the machine through all the suggested ringers when I get the new memory! I suspect from what I've read here, though, that I may not even be able to get to the boot stage given how different the new sticks are from the old in model and specs!

Absolutely. :thumbup:

Ok!

 

(1) Memory arrived and installed.

(2) First boot was a no go: power on and off cycles.

(3) Removed all sticks and firmly reinstalled them. Then it made it through to the boot.

(4) On boot, was told that my OC failed and I had to go through set up. I reset my overclocking to auto and memory AI profile to auto. Again with the power on and off cycling!

(5) Cold boot luckily got me back to UEFI. Then I reset everything to factory specs and noted that the various DRAM settings such as voltage, latency, etc. was reset. I did not change any of this myself, but I did go through the motherboard EZ Overclocking wizard once a long time ago and remember the DRAM settings changed. No idea why it was not reset when I set the memory profile to auto. Anyway, this one did the trick: successfully booted to desktop!

(6) Rebooted into the Ultimate Boot CD and ran MemTest. All passed!!! YAY!!!

(7) Back to UEFI, and set memory AI profile back to XMP in preparation for re-overclocking.

(8) Boot to desktop to run IntelBurnTest on Very High: cleared!

(9) Currently, running Aida64 now (how long? an hour?)

 

So, so far, so good.

 

Here is the curious thing. My default clock is 4.0. I had previously overclocked it to 4.5. Running the tests (8) and (9) show that the max CPU clock is at 4.4. I assume that this is the "turbo" mode?

 

So the question is: if the default/built-in turbo mode gets me to 4.4, is it worth it to manually overclock if all I can pull out of it is 4.5 max?

 

I remember reading somewhere that turbo mode accelerates one CPU at a time, so if any application uses multiple CPU's then manually overclocking will still be beneficial even if you don't exceed the speed of the default turbo mode. Is this true?

Stability vs Performance you will need to decide here.......

 

But to answer your question what Intel CPU are you running and always check here first - http://www.intel.com.au/content/www/au/en/homepage.html

 

Find the correct CPU and model and find the info needed as an example - http://ark.intel.com/products/97128/Intel-Core-i7-7700-Processor-8M-Cache-up-to-4_20-GHz

 

Always pay attention to Intel's specs and warning limitations on their webpage dedicated for system builders, some boards will inherit features others will reduce or nullify them due to board limitations.

 

Also ensure your MOBO can support OC and has plenty of overhead room for increase in things like voltage - http://dlcdnet.asus.com/pub/ASUS/mb/LGA1150/VANGUARD_B85/E10276_HDMI_insert_for_web_only.pdf?_ga=1.26310397.1179871197.1492878386

 

Dont cook the mobo socket just to have more CPU Gigs, you could blow your MOBO go through everything from scratch and ensure that all is okay and permissible without damage to any parts.

 

 

You should have the entire case stripped and working on a rubber mat with the minimum hardware and testing the upgrades and tuning/tweaking the voltages and settings on CMOS screen before entering Windows.

 

Also you can use MEMTEST in DOS mode which is far better than any window app.

 

If in doubt visit places like Tomshardware for support they do heaps of bench testing - http://www.tomshardware.com/ :thumbup:

Thanks!

 

I have an i7-4790K: http://ark.intel.com/products/80807/Intel-Core-i7-4790K-Processor-8M-Cache-up-to-4_40-GHz?q=Intel%C2%AE%20Core%E2%84%A2%20i7-4790K%20Processor%20(8M%20Cache,%20up%20to%204.40%20GHz) .

 

which says, regarding the 4.4 "turbo" mode: "Max turbo frequency is the maximum single core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology."

 

So it looks like it might be worth overclocking after all to get 4.4 or 4.5 on all cores simultaneously (or, at least, more than one core at that speed at the same time).

 

Motherboard is Sabertooth Z97 Mk i: https://www.asus.com/us/Motherboards/SABERTOOTH_Z97_MARK_1/ .

 

For the previous overclock, I've been running at Vcore of 1.2 for a while now. Cooler is CM Hyper 212 EVO.

I think you should search for the Intel CPU Engineer MSD PDF for your Processor before you cook your MOBO due to heat issues.

 

Like this here:- http://www.intel.com/content/www/us/en/processors/core/core-technical-resources.html

 

Be safe and learn about the chip and socket design before voltage increase they get hot especially if no water cooling or other source of cooling.

 

:mad: Hot is not good so you will need to check temperatures and use good CPU paste before anything.

 

Also CPU's exceeding OC can become unstable and cause irregularities like shut downs so forth so people should read all docs before OC to be sure and safe.

 

Look on internet for cooked MOBO's and CPU's damaged due to incorrect use........ awareness as caution for preventative measure is always good when OC PC's.

So the question is: if the default/built-in turbo mode gets me to 4.4, is it worth it to manually overclock if all I can pull out of it is 4.5 max?

 

4.4Ghz to 4.5Ghz? I'm afraid that you will see no difference. That's not worth the effort. Try the game (at 4.4GHz) and see how it goes.

 

Below 1.3v (with "medium end" air cooler) is safe for every day use. Stay below 1.35v. Stock voltage at 4.4Ghz is around 1.2v.

 

I run Prime95 (8-12 hrs min.) for stability when I overclock. I always overclock the CPU by the mobo bios.

 

I remember reading somewhere that turbo mode accelerates one CPU at a time, so if any application uses multiple CPU's then manually overclocking will still be beneficial even if you don't exceed the speed of the default turbo mode. Is this true?

 

No.

 

Install CPUID HWMonitor, and monitor your stuff. Vcore, Core clocks, wattage, etc.

Thanks! Yes, I discovered this myself by doing exactly what you suggest.

 

As things stand now, I am considering upgrading the CPU/MOBO to a i7-7700K + MSI Enthusiastic Gaming Intel Z270 combo to get more performance!

[Demon_]

No. It's not worst the money. The i7 4790K is excellent. I still run my i7 3770K at 4.4Ghz.

 

 

If you have money to lose... What is your resolution? Video card? HOTAS? Pedals? Monitor? Your truck?

I have a Gigabyte 1080 Ti Gaming OC. I could run with everything maxed on my 4K without problem. This issue is in VR. With the CV1, I can pull 90 FPS a lot of the time and 45 FPS in others. But there are some times that I crash into the 22-23 FPS. And nothing I have tried settings wise gets me out of that. From this discussion (https://forums.eagle.ru/showthread.php?t=186730) it seems the CPU upgrade will help?

[Demon_]

The CPU utilisation is at 25% because the game uses one of the 4 cores. The CPU is used for the AI, and the ASW of Oculus. It looks like DCS is not optimized for CV1...

 

Maybe you need to lower some video settings to get +90 FPS, to prevent the activation of the ASW. But you already tried that..

 

i7 4790K to i7 7700K? The performance gain will be very small.

That makes sense! I though this might would also explain why the other guy is getting 90FPS where I am getting 22? While we are both using just one core, i.e., his single core is doing a much better job than mine?

Yep, not much change.

Ah, really? This makes me strongly reconsider :( :( :(

Yes. With emphasis on very.

 

See image from https://www.cpubenchmark.net/singleThread.html

 

Less than 3%

Ah, thanks, you all (BitMaster included) have saved me $1K! I was hoping that the CPU upgrade would solve the 22FPS, but it appears that this would have been quixotic!
